Tactical AI still moves by one tile until it can hit you in one move. It is not optimal. In most cases it is more optimal to move at maximum all the time. For example, Magnar without horse attacks Slag. Slag moves by one tile until he can hit Magnar in one move. All this time Magnar shoots Slag with spells.
[0.992] Issue still persists. Monsters move by one tile. You can cast several spells before actual fighting: Shrink, Growth, Blind, Curse, Haste, Slow.
