SPELL RELATED
- Tenser's Trans - You become an engine of destruction, gaining the following benefits: +4 Strength, +4 Dexterity, +4 Constitution, +4 Natural AC, +5 Fortitude saves, Proficiency with Simple and Martial Weapons, 100% spell failure, and an attack bonus equal your hit dice minus your current BAB. You do not Polymorph anymore.[/quote]

Will this spell failure be negated by the Automatic Still Spell feats the same way armor and shield spell failure is or will wizards and sorcs still not be able to cast when this spell is active? If the former is true then zomg i need to get my armored caster build going!
