Another new 8th level spell, Enhancing the Divination school Options

[Sikret]

Here is an idea for a new 8th level spell of divination school. Comments are most appreciated.

Note that if we decide to implement the other new divination spell, Premonition (either as a replacement for Mislead or not), these two spells need to be rebalanced together (and should not cumulatively work with each other).

Foreknowledge (Divination)
Level: 8
Range: 0
Duration: 1 turn
Casting Time: 8
Are of Effect: Self
Saving Thorw: None

By means of this powerful spell, the mage can foresee the events of the immediate future to some considerable extent and can prepare himself (both mentally and physically) for the events which are going to happen. The mage gains +4 bonus to Armor Class, +1 bonus to THAC0 and saving throws and +1 bonus to casting speed for the next 10 rounds. These effects will remain for the spell's duration and won't be dispellable.

I'm glad you are looking at level 8. Level 6 has PfMW and PfME. Level 7 is ruby ray. Level 8 is ... wilting? - not in IA for the most part. So, Level 8 could definitely use some beefing up. The spell that you propose could be good for melee mages, but I doubt it. PfMW works much more reliably. I'm not sure that a +1 casting time for 10 rounds is worth a level 8 slot to a casting mage.

I'm not sure that a +1 casting time for 10 rounds is worth a level 8 slot to a casting mage.

When combined with other casting-speed increasing items (Amulet of Power, Robe of Vecna, possibly Gloves of Spell Weaving from The Four) that extra +1 could prove deadly in the right circumstances (i.e. when using Improved Alacrity).

I think though that the bonus to THAC0 bonus and saves bonus should both be slightly higher, maybe +2. As a small detail I think Immunity to Backstab should be added as well.
