Wyvern Call

Wyvern Call summons a wyvern to the wizard's aid. 
==Description==
==Gameplay==
The caster designates a point on the area map where the Wyvern will spawn, using the targeting cursor.
When the spell is cast a swirling magical circle animates at the designated point, lasting a few seconds and then the Wyvern appears.
The creature is a green circled one, that may be controlled and ordered where to move, and who to target.
The creature will disappear from the map when the spell's duration ends, and if it is killed, will leave behind a corpse.
Like all summoned creatures, the Wyvern cannot transit to another area map and has to remain on the one it is summoned to.
A Death Spell will kill it instantly, as will entering into a Death Fog cloud.
==Summoned Wyvern Stats==
*Hitpoints: 63
*STR: 14 (all other stats: 9)
*AC: 1
*THAC0: 10
*2 attacks per round
*Deals 2d8 crushing damage
*The wyvern may choose to use a different attack, inflicting 1d6 piercing damage and a Poison effect causing 5 damage per second for 20 seconds unless the victim succeeds with a Saving throw vs poison with a -4 penalty. Multiple poison effects stack with one another for great damage potential.
*Both types of attack are considered +2 weapons.
*One weapon is picked at random and kept for 12 seconds before a choice is made again. (60% chance to pick the poisoning weapon.)
*The wyvern is immune to Hold, Level drain, Paralyze, Slow and Web effects.
*In Enhanced Edition, it is also immune to Entangle spells and a Green or Black Dragon's Plant Growth.
*Save vs death/wand/polymorph/breath/spell: 7/9/8/9/8.
==Notes==
-This wyvern can also be summoned once per day by any class except Wizard Slayers via the Book of Infinite Spells.
-The main advantages of this summoned beast are its list of immunities (that includes some rare ones among non-undead summons like Hold/Paralysis and Level Drain) and its very effective poison damage rate (for example, two mere applications can kill Firkraag or just one if the dragon is hasted, as hasted enemies take more poison damage).
-The wyvern's low strength value means that spells which raise strength are more valuable to the wyvern than other summoned beings with better initial strength values. For example, a Cleric's Strength of One spell (that can be used to buff several wyverns at once) will improve THAC0 by 2 and damage by 3.
-A wyvern also benefits from improved haste more than most summons, as the majority of them only have 1 attack per round (so there's no point in doubling 1 with improved haste, might as well use regular haste), but the wyvern has 2.
-A Skald's song and/or any Bard's Enhanced Bard Song can do a lot for this creature, as its main issues are AC and THAC0 (not to mention the relatively short duration of the spell). In fact, if both songs are combined the wyvern will reach -7 AC and 2 THAC0, so if there are several wyverns it's pretty likely that even very strong enemies will get poisoned and die (again, just two applications can fell even dragons).
-A Skald's song or Enhanced Bard Song also provides immunities that fit perfectly with the wyvern's own, adding fear, confusion and stun to the list, making wyverns immune to the vast majority of status effects in the game (one of the few notable exceptions is charm).
==Bugs==
*In the original edition, if the wyvern stays idle it may revert to its non-poisoning weapon at any time, so keep it busy. This weapon switch does not push back the running 12-second delay before a "normal" weapon switch occurs though.
==Where to obtain its scroll==
-Unlike most spells below level 9, the scroll for this spell cannot be found on random loot.
