Fixed NPC_STONESKIN, NPC_ANTIMAGIC, NPC_MAGICMIRROR and Autocast on magic hit
- Fixed NPC_STONESKIN, NPC_ANTIMAGIC, NPC_MAGICMIRROR (bugreport:6118, bugreport:9375)
  * Using the skills will now be 100% successful (can't be resisted)
  * Fixed skills not working for players (e.g. Ulfhedinn, Mithril Magic Cape, Platinum Shield)
  * Fixed level 5 and 10 not working at all
  * NPC_STONESKIN and NPC_ANTIMAGIC will no longer change DEF/MDEF, instead they will increase/reduce physical/magical damage percentually, this IS official behavior
- Fixed "Autocast on magic hit" having its chance halved (bugreport:9377)
add new scriptcommand
- dispcolor or displaymessage
displaymessage("<message>"{,<color>{,<Account ID>}})
now you can send message with color to player
Hex color see more : http://www.colorschemer.com/online.html
No cell stacking implemented (official version) (bugreport:9378)
- Split config cell_stack_limit into custom_cell_stack_limit (previous feature) and official_cell_stack_limit (see below)
- Expanded map_count_oncell by a flag parameter, currently only one flag is supported: only count standing units (needed for official cell stack feature)
- Added a new function map_closest_freecell that will return the closest free cell using the same order that official servers use
- Monsters will now actively search for a free cell when starting to walk randomly and when unlocking target
- When any unit finishes walking (regularly) and is not on a free cell, it will now actively search for a free cell
- Step actions will be delayed until a suitable cell was found, they will even be executed when the player walked slightly out of attack range

Plant damage, Land Mine, minor fixes and improvements
- Fixed up the damage code in regards of damage against plants (bugreport:9380)
  * Rewrote DAMAGE_DIV_FIX so that it rounds damage down when number of hits is negative (damage split on hits)
  * Created a function battle_apply_div_fix that does not only call DAMAGE_DIV_FIX but also makes sure that damage can only become 0 when the custom config setting skill_min_damage is not set for the current skill type
  * skill_min_damage is now 0 by default (official: all types can fail against plants as long as skills have negative number of hits), if set, all skills will deal as much damage as hits
  * Restructured and renamed function now known as "is_infinite_defense" that will work for all 3 damage types and returns if damage is infinite for the current situation, it will now also properly consider all "MD_IGNORE" modes
  * Fixed the order of processing of all 3 skill types in regards of plant damage: first all calculations are done, then plant damage is applied and then DAMAGE_DIV_FIX is applied
  * Sonic Blow and Rapid Shower are now skills with negative number of hits (i.e. they can't hit plants officially)
  * Traps can no longer ignore plant mode (only way to damage plant more is via status changes)
  * Final Strike is now able to hit plants (deals 1 HP damage)
  * When left-hand-wielding, you will now always deal 2 damage to plants per attack, regardless of whether double attack triggers or you don't even have a weapon in the right hand
  * There will no longer be backhand damage to plants (Katar)
- Land Mine is now a single target skill, the trap still triggers in a 3x3 area, but will only hit the first target that touches it (issue:99)
- Changed the "Don't return reflect damage" flag from 0x1000 to 0x1000000 as apparently the other flag was already used; updated function description so it's easier to see
- Improved SC_SIGHTBLASTER structure slightly
- Typo fixes and description improvements

- Revert skill cooldown list not support found problem map server crash.
I will try check again.
* Fixed #101 - Warg Dash not beginning run action when used.
Timer interval, Waterball, Crimson Fire Formation and boss walk delay updates
- Reduced the timer interval from 50ms to 20ms (official value)
  * For a long time it is well known that the Aegis interval is 20ms, but devs have been hesitant to set it to that out of performance reasons; these days however, machines are better and there aren't really many 2000+ player servers anymore, so a 20ms interval is actually quite viable now.
  * Setting the interval to 20ms makes the server perfectly in sync with the client that expects the server to have a delay of no longer than 20ms.
  * All skills that are "chain-able" on official servers will now also be 100% chain-able here (previously it just worked to 40%), assuming there is no lag
  * Skills with cast time will no longer go off 30ms later than officially
  * Several others improvements in regards of client-server sync (timers are used almost everywhere)
  * This might increase the CPU usage by up to ~50%, if you have trouble running your server with this, you can increase it again in timer.c (TIMER_MIN_INTERVAL)
- Strongly improved the Waterball implementation (bugreport:9382)
  * The interval between Waterballs is now 150ms (previously 125ms); due to the timer interval it will alternate between 140ms and 160ms (yes, this is official)
  * While the Waterball effect is active, players and non-boss monsters can no longer walk
  * Added a server-sided canact delay each time a Waterball is shot, which is equal to the one the client gives; this is to prevent hackers from being able to mass-cast Waterball; you can still multi-cast Waterball if your aMotion is shorter than the Waterball interval (i.e. 186 ASPD or higher)
  * The Waterball effect is no longer canceled when the target hides behind an obstacle, but no waterballs will fly and no damage will be applied; walkdelay will remain, but there won't be any canact delay for the caster (meaning he can cast another spell); if the target comes out of its cover during the duration, it will be hit again (this also fixes an exploit against MVPs)
  * Waterball now has a max duration of 10 seconds, even if more water cells are available, the effect will stop; this means that level 10 monster water ball will now only hit up to 67 times
- Fixed Crimson Fire Formation having a knock-back effect although it shouldn't (bugreport:6949)
  * It will hit once every 20ms with no knock-back, regardless of whether the target is undead, non-undead or a player
  * If you want to it to display more "fluently" you would need to set the SKILLUNITTIMER_INTERVAL in skill.c to 20ms, but the performance loss is pretty big for something only this skill and Firewall would benefit from
- Bosses are now able to ignore skill-induced walk delay (#100)
  * They can for example walk after casting Sonic Blow and Waterball (see above)
- Minor description improvements
- Fixed item bonus for vesper card in pre re
- Fixed warning for infinite warp where count_rewarp increased when the player was warped near a warp

Land Protector, Ground Skill Splash, Storm Gust Knock-back
- Land Protector now behaves like on official servers (bugreport:5237)
  * Land Protector now protects from units being placed on it, no matter if they have splash range or not
  * Land Protector no longer protects from damage from units not outside Land Protector that splash inside
  * Meteor Storm no longer shows meteors falling if they would land on Land Protector
  * Pneuma can no longer be placed next to Land Protector
  * Also cleaned up the code a bit, so the checks are done where they should be done
- Ground skill splash ranges updated to their official values (bugreport:5237)
  * Lord of Vermilion places units in a 11x11 area with 3x3 splash range each
  * Storm Gust places units in a 9x9 area with 3x3 splash range each
  * Heaven's Drive places units in a 5x5 area with no splash range
  * Venom Dust now has a splash range of 3x3 and is consequently larger than before
- Storm Gust's knock-back behavior updated to official (bugreport:5237)
  * Each of Storm Gust's units will knock back "Away from center"
  * As units in the south-west are processed first, the knock-back direction will usually be north-east
  * At the edges the knock-back direction will be "to the outside"
  * Land Protector and Ganbantein will influence the knock-back behavior strongly, e.g. if Storm Gust has a hole in the middle, it will have a "suck in" effect
  * Added a config option for those who want the old "random direction" behavior from eAthena
