An exciting update for Arelith as we update our spells lists to include many D&D spells previously not present in NWN, and provide an updated spell list to many existing caster classes!

Please note that all of the below are subject to change as this includes a lot of new spells and adjustments to existing spells.

First of all, most, if not all, of Arelith's spell specific changed will now be shown on the spell's in game description (Not scrolls). These changes could already be found here:
http://wiki.arelith.com/Spell_changes

If I missed something, typo, or needs clarification of the In-game description let me know and I will look into it.

New Spells!

Please note a full explanation of these spells can be found on the in game spell description.

Wild Mage

-surge and -chaos commands/feats has been removed in favor of 3 new Wild Mage specific spells (More on them below).

A spell replenished (Or Greater Wild Surge) has been removed to replenish a spell from artificial means, e.g Nahal's Reckless Dweomer, but can still be replenished from a regular passive 5% Wild Surge occurence.

The -fate command still works as it used to.

On top of this a number of Wild Surges has been drastically reduced in their effectiveness. There are too many to note here but some of the main culprits are:
Combat Ready, Spell Resistance and Ghostform. I will go over more of the surges (And add new ones) in a nearby future as well as monitoring the Wild Mage class to make further changes.

Surge 55 changed to Spell Replenished (Replacing Hindsight; Will not work with Fate)

Wild Mages will receive Nahal's Reckless Dweomer, Chaos Shield and Improved Chaos Shield automatically to their spellbook.

Status Effects:

Sickened (Curse)
The character takes a -2 penalty on all attack rolls, weapon damage rolls, saving throws, skill checks, and ability checks. Can only be removed by Remove Curse or until it expires.

Nightmare (Curse)
Nightmare prevents sleep and will give -2 STR & -2 DEX. Creatures currently sleeping/resting or under the Sleep spell will wake up if they are affected by Nightmare.
Creatures immune to Sleep (E.g Elves) are not affected by Nightmare. Curse is permanent until removed by Remove Curse or Greater Restoration.

Final Note
This was a lot of work, especially updating the copy of existing spells with Arelith specific changes. I am well aware some of these will change and be tweaked as we go forward and I ask players to be patient and respectful with their feedback and I will quickly adjust things as we see fit. This is a big update so requires a lot of testing so please do your best in in providing any valueable information about the new spells and spell adjustments.

Finally none of the new spells are available in merchants as of yet but will be populated as we go in the coming days; all of the new spells can be scribed (Save the Wild Mage specific ones) so I understand this will be limited to certain players.

Thank you!
