Engine specific notes:
Engine specific notes:
• PST creature disguises are not stored as a field in the creature file, they are held as a GLOBAL variable, named 'appearance'. A value of 1 equates to zombie disguise, a value of 2 equates to dustman disguise.
• Several fields for TNO are generated dynamically, and as a result changing fields in the relevant CRE file will have no effect.
• Several fields for TNO are generated dynamically, and as a result changing fields in the relevant CRE file will have no effect.

NB. Lore is calculated as ((level * rate) + int_bonus + wis_bonus). Intelligence and wisdom bonuses are from lorebon.2da and the rate is the lookup value in lore.2da, based on class. For multiclass characters, (level * rate) is calculated for both classes separately and the higher of the two values is used - they are not cumulative.
