Dear SD.
We need more information in tactical battle. You're certainly in the process of rewriting it for multiplayer (wink).
Can you expand the description in tactical battle in the bottom right. when hovering over enemy, there is a chance and damage ranges already displayed as well as information if the target is voulnerable/resistant to weapon type.
Can you expand it further i.e. base attack 20, +3 to attack due to initiative higher then target, multiplied by 2 due to overpower etc.. all those situational bonuses that are applied but are not displayed anywhere and nowwhere to be taken into account.
yours faithful
