How it's done.

Bigby's Helping Hand is designed to ease the load on the DM during battles in the AD&D game system. It does this by tracking the die rolls of monsters for attacks and damages while still allowing the players to roll their own. It also tracks initiative roll and this is used along with weapon speed to select the next attack. Curently there is an option to include a Dexterity bonus to the initiative (As per the reaction adjustment).
