Summon Magic / Charge / Wands&Staffs / One time spellbooks / New Apprentice

---

Summon Magic:

This new wizard spell works much like summon guns except it instead brings the crew magical tools and weapons. There are preexisting artifacts (minus some that would cause huge confusion/balance issues) as well as new spellbooks, wands, and a staff. The chance of survivor antag is the same as summon guns.

---

Charge:

This new spell allows for the recharging of otherwise unrefillable wands, but there's a heavy chance that the total number of charges will decrease with each casting until eventually they're impossible to keep recharging. As a bonus the charge spell can also be used to charge batteries and things that run on batteries (such as energy weapons). This carries the same max charge weardown penalties however. Lastly this spell allows a wizard to charge other wizards with a grab, reseting their spell cooldown. They cannot use it to charge themselves. It has a 60 second cooldown.

The wizard cannot buy this spell himself, it only comes randomly to the crew during Summon Magic and with the new apprentice loadout.

Wands&Staffs:

Magic weapons have been overhauled into their own catagory so there won't be any more weirdness with batteries in staves or apparent magic resistance on things that reflect energy weapons.

Wands have been added, these wands come precharged with a number of shots that can be fired off at their leasure but cannot be recharged once emptied (unless the charge spell is used). They come in a varity of exciting flavors:

*Death: Slays instantly but has very few shots (1 to 3)
*Resurrection: Revives and/or heals instantly but has very few shots (1 to 3)
*Polymorph: Same function as the staff of change
*Teleport: Weaponized blink spell that doesn't respect space tiles and can also warp away machinery or items (but not turf)
*Door Creation: Puts easy access wooden doors in walls
*Fireball: Same function (but slightly lower damage) as the fireball spell
*Nothing: Lame and useless

Wands can also be used on the user (unlike staves) by clicking on them. Warning messages have been added to a few wands so people don't accidentally zap themselves with the wand of death unless they really want to.

Wands cannot be aquired by the wizard directly, and are only spawned during castings of summon magic.

There is also a new staff, the staff of healing, which works as a recharging version of the wand of resurrection. The new apprentice starts with one of these, and they can also be found during summon magic. The wizard cannot purchase it directly, and as a stave he could not use it on himself anyways.

One time spellbooks:

Found exclusively in summon magic are one time use spellbooks that can teach any player a robeless spell. Once read the book vanishes.

Books come in the following flavors:
*fireball
*smoke
*blind
*mindswap
*forcewall
*knock
*curse of the horsemen
*charge (described above)

New apprentice:

A fourth loadout for apprentice wizards has been added. This wizard is intended as a support role and comes with forcewall (for cover) and charge (used to keep him and the wizard well stocked in laser weaponry or to restore the wizard's cooldowns). It also comes equiped with a free Staff of Healing for keeping the wizard alive. Shoot the medic first folks.
Adds all sprites for all wands, books, and the staff of healing
Fixes an issue where someone spamming a wand might lose charges without actually firing the bolt
Removes a few missed bugtesting lines
Adds a var (variable_charges) to be disabled for wands with assured max charges for future use
Code optimization and copypasta removal:
the teleport wand now uses do_teleport
the polymorph wand now uses wabbajack in both instances

You can now click on yourself while holding a wand to cast it on yourself in addition to clicking on the wand itself.

Changed how guns/magic are given out slightly. Previously no antag could get a gun/magic thing (including survivors made by the spell in the case of multicasting) but now antags who aren't the wizard or an apprentice of the wizard also get one.

Fixed a few bugs on accidentally burning charges by click in places tht wouldn't actually fire the wand/staff
Suggestion implimentation patch!
*Span classes the whole update
*Spellbooks no longer vanish after being used, instead used spellbooks now have various bad effects should they be attempted to learned from again (the original reader won't acidentally fall to this, as they will just say "I've already read this"). Leave em out as traps for people or properly dispose of your trash! Or...
*The charge spell can now attempt to recharge one use spellbooks so someone else can learn the spell. This only has a 20% success rate and will destroy the book should it fail (even if the book was actually unused). You can't attempt this on the wizard's spellbook
*The "staff of nothing" (functional) placeholder now uses the generic staff sprites
*Spellbooks can now be placed in bookshelves just like normal books
*The teleport spell won't yank anchored things anymore, but as a consolation it will warp the entire contents of a tile should it be targeted. The code has been tweeked so this shouldn't effect the server too bad even if large numbers of items are warped to unique locations this way

A small change to how wizard rounds end when continuous wizard rounds are off:

After the game has determinded that the wizard is dead it will check if there's any traitors alive. "Traitors" in this instance means apprentices and survivors the wizard may have created with contracts/summon guns/summon magic. Thus if the round still has a chance of being interesting (survivors) and/or the wizard has a legitimate chance at revival (apprentices) the round keeps going.
