[K1] Scripting and Criticals

[ShepardCommander]

Hi, does anyone know of a function I could use in a heartbeat script to increase critical multiplier? Been using the source scripts from the multifire mod to teach myself how to apply conditional attack, damage and defence bonuses based on feats present and items equipped and have all the rest of my changes tested and working but I just can't find any function to edit critical threat or multiplier. Alternatively any way to apply effects to weapons in such a script (so as to slap a Massive Criticals effect on if my condiitions are met)?
