http://slickproductions.org/forum/index.php?topic=425.0Slow certainly seems to have an impact, although it seems to emphasized with slower characters in the party.
It seems to only max out twice according to the math. Speed can be slowed down by a max of 16 more points. The item that slows down targets (Spider's Silk or whatever it is called) maxes on this aspect. Slow (spell power of 8) needs to be cast twice to max it as well. These values seem to factor against Agility to an extent (unlikely involving multiplication, but more of a cumulative effect).
I will have to check Slow against Split targeting though to be sure.
Similarily goes with Haste/Fast, but with a lesser impact. You can only max it out twice as via the Haste/Fast spell. Haste decreases the critical value by 3. The item that hastes the item user (Hermes Shoes) attempts to decrease the value by 8, but the cap is at 4 only.
The math against the internal value is easy (I thought it was some magical formula, but obviously I was wrong). If the value is > 128, 256-spell power for use in subtraction... Otherwise, use that spell power value for addition.
We have EVEN MORE themes now, but some old ones are gone...
