If no weapon is found, gloves are merged (if the weapon is found and bracers are equipped, properties from bracers are merged)
If the shifter is wearing a ranged weapon, its related ammo slot is taken and merged into the shifted creature weapon/s (NOTE: ammo created from the "Unlimited Ammo" property on a ranged weapon are NEVER merged)
If the polymorphed shape doesn't have a melee weapon, the shifter weapon properties are merged into ALL creature weapons, if the creature has claws and bite.
AC is only applied once, the highest value on items is merged.
Bonus from items about abilities, skills, saves, so stack up to their caps.
The monk class cannot be used to gain Wisdom AC bonus or Monk AB progression while shifted.
Each shape will get an addition Armor AC bonus upon shifting (check the sheet below for more info). The AC is based on the polymorph type. Tenser Transformation and Shapechange have their own scaling, check Spells Changes for more info.
When a character reaches level 30 in the Shifter class, shifter related shapes will get improved, also the shifter gets 1 addition attack per round.
All shapes get additional AB and Armor AC bonus if the character has Spell Focus Transmutation feats: +1 for Spell Focus, +2 for Greater Spell Focus, +4 for Epic Spell Focus. For pure shifters, Spell Focus gives +2, Greater Spell Focus gives +4 (a pure shifter cannot take Epic Spell Focus).
Leveling while shapeshifted is forbidden! This, to prevent some possible character bic file corruption. Unshift before leveling up!
