MAJOR UPDATE: 27 January 2011

- fixed override version which DIDN'T WORKED BEFORE! Please download the new version and overwrite the old.
- fixed few spell scripts that couldn't be recompiled
- fixed nw_i0_spells library which was outdated (from Rabidness package :/)

I do have done every spellfixe that I have found and fixed myself, I found sad there no fix on monster ability that need to be fixed also. Well that it.

If you find any bug simply tell me here. If you find any wait to make a better fix tell me here ;p and if you find another bug I could fix it and add it. Took me about two hour to make, tested everyone of them so that should be fine.

Every line modified have either a //Bug fix or something for you could know exactly where is the fix in case of custom script in your module.

There only Rabidness AoE work that has been added from someone else then me. It can be found here : Link

Note by Shadooow

This package started a development of the Community Patch Project where I rewrote all the spells from scratch to fix engine issues. In this process I have found numerous new smaller or bigger issues even with already modified spells in this project. Also I have found that some of the fixes here has its own issues. This is specifically the case of circle AOE fixes from Rabidness which fails under specific conditions (ie. two auras on different objects from same caster colides with each other).

Therefore this project is no longer supported by me and shouldn't be used. Instead you should use Community Patch which contains all of this + more fixes and performed in a better way.

Also the format of this package is ERF which means that importing this into your module will ask you for overwrite and if you allow it you might lost your own modification. While spellchanges from Community Patch will not take effect for any spell you modified in your module. In either case you need to merge conflict scripts anyway.

Differences between this package and Community Patch spell changes (excluding additional fixes):

- entangle dexterity bug fix has been removed. The workaroud was too ugly, messy and not reliable enough to be worth it.
- multisummon exploit in timestop fix has been removed. Timestop has different effect in multiplayer so it cant happen there, in singleplayer let players to have some fun
- storm of vengeance still deals 6d6, instead description has been updated
- searing light - not changed
- trickery domain - not changed
- flame arrow - SR check still per each missile. However this spell was rebalanced in different way by giving spell immunity priority over spell mantle, this means that this spell cant be used as an ultimate low lvl tool for bringing down spell mantles if the target is also warded by globe of invulnerability, immunity to conjuration school or natural immunity to spells of lvl3.
