Blood Homunculus is still not applying any buffs from Spell Foci and/or Epic Caster:
Pictures shown for Tier 3 summon, and the first attack in its flurry.
With a +19 STR modifier, and +16 BAB, that is 35AB Base. No +5 from 'sure strike' whatever that is. No bonuses from epic (CL 24. Character/Caster level is 30, but with Shadow Weave, so -6 on transmutation. Not sure how that affects epic bonuses). No bonuses from transmutation foci (Caster for this has ESF: Transmutation).
I suppose this would indicate that SOME bonuses are being applied, but the attack decrease is there for some reason?
AC was also severely nerfed in the last update and wasn't recorded in updates, not sure if that was intentional or not. Icon also isn't fixed since last update.
