Both the Epic Drow and Drider forms for Shifter appear to have a very short duration on their Darkness spells, much shorter than (Shifter + Druid levels)/round.

After experimenting with spell-like items, it appears to last exactly 5 rounds. (It expires in the same time as a haste potion.)

Of course, that's just my opinion, I could be wrong.

Can confirm this only last 5 rounds.

Tested as Epic Drider with 25 caster levels.

Fixed for next update.
