Spell fixes
-Several fixes to Animal Trance spell
*will use caster level, instead of total character level, for duration (if not racial ability)
*won't have oversized radius (feet values in script should be converted to meters)
-Fixed Dispel Magic and all its variations, so that when targeting area, it won't try to dispel aura effects twice (both as an area of effect object and as an effect on creature). Also, dispel check for area effects is changed to match official 3.5e rules better. Fixed spells/invocations are: Dispel Magic, Lesser Dispel Magic, Greater Dispel Magic, Mordenkainen's Disjunction, Voracious Dispelling and Devour Magic
-Fixed Divine Power, so casting it twice on same target won't remove increase to base attack bonus
-Tweaked Enlarge Person (including Duergar version) and Righteous Might, so extra damage added isn't magical, but physical. Otherwise, as magical damage, it would bypass any damage reduction
-Fixed Entropic Husk, so that creatures immune to mind affecting effects properly turn hostile on their former allies
-Fixed Flee the Scene invocation, so it functions normally if having Team Rush feat (won't haste only 2 characters)
-Fixed Grease, Entangle and Vine Mine spells, so that incorporeal creatures are properly unaffected by them
-Fixed Iron Body, so it makes caster immune to Mass Drown spell (and not just Drown)
-Several fixes to Mass Fowl:
*mental stat penalties, added by spell, made extraordinary to prevent their dispelling
*properly removes invisibility from caster, when used
-Fixed both Mind Blank spells, so they remove mind effects from Tasha's Hideous Laughter and Solipsism spells
-Fixed Vampiric Feast, so it properly removes invisibility from caster, when affecting enemies
-Fixed all restoration magic, so it doesn't remove buffs from Reduce spells. This includes: Lesser Restoration, Restoration, Greater Restoration, Neutralize Poison and heal by NPCs
Fixes to feats and class abilities
-Fixed Fey and Fiendish Legacy/Presence feats, so that duration depends from total character level, and not from the level in class, which was leveled up, when these feats were taken
-Several fixes to Song/Hymn of Requiem:
*hymn will heal properly when used NPC AI
*won't affect creatures of same faction that are outside current area
-Several fixes to Eldritch Chain, when used with Hellfire Warlock:
*Constitution damage will be reported, if any of chain attacks misses
*will report correct Constitution damage, if more then 1 point is lost
-Fixed several issues with Hellfire Blast and Hellfire Shield:
*removed exploit which allowed use of Hellfire even if having immunity to Constitution damage *Constitution damage from use of Hellfire won't be dispellable anymore
*Hindering and Binding Blasts will apply Hellfire Blast damage when active
*Hellfire Shield won't halve damage with failed saving throw anymore, and do full damage with successful one *Hellfire Shield will respect Evasion
*Hellfire Shield won't show fire impact visuals, if no damage is inflicted
-Fixed several issues with Warlock essences, which happen when they share same shape:
*applying new essence won't remove old one of different type, if both are using same shape
*essences with secondary damage (like Brimstone) will work, if target is already affected by some other essence that shares same shape -Fixed Utterdark Blast shape, so it's properly set as Supernatural (and thus, not possible to dispel)
-Fixed Warlock's Imbue Item ability, so it works with all recipes from MotB
Other fixes
-Added workaround for an issue, when taking epic spells with prestige classes could lead to getting wrong ability modifier being applied to their save DC. Also, added missing DC bonus to epic spells normally gained for every 3 caster levels after 20, as well as DC bonus awarded through influence feats from MotB campaign
-Item properties without subtype will be upgradeable through crafting, if max number of enchantments is already reached (works with all 3 crafting systems)
-Fixed crafting in SoZ campaign, for REAL, so that Imbue Item can substitute any spell needed -Fixed infinite loop in Fatal Sonic Trap script
-Several fixes to Unity of Will spell-like ability of Silver Sword, used in MotB campaign:
*depleting temporary hit points won't cancel out other buffs
*enemies immune to mind effects won't skip saving throw and get penalty anyway (should be immune instead)
Fixes to spell attributes
(spells.2da)
-Fixed Castigate, so it can be properly aimed on caster, instead his allies (and effect is centered on caster anyway)
-Added area targeting marker for Magic Circle against Alignment, since it's area effect (SoZ only)
-Fixed range for Shadow Conjuration version of Darkness, so it matches other Darkness spells/abilities (should be large, not touch)
-Added missing verbal component for Utterdark Blast invocation (NWN2 only)
-Added area targeting marker for Assassin's Darkness, that was missing
-Fixed Barkskin, so it can be scribed on scroll with Ranger (NWN2 only)
-Fixed Detect Undead, so it doesn't give item with Mass Cure Serious Wounds, when making potions or wands (NWN2 & SoZ only)
-Fixed Magic Circle against Alignment, so it gives proper scroll when scribed (instead of Protection from Alignment, NWN2 only)
-Fixed Mass Charm Monster, so it can be scribed on scroll with Wizard (NWN2 & SoZ only)
