Round table

Please tell me how to calculate damage. In FiZmiG it is written extremely incomprehensibly. Well, for example, take this scenario. Essentially, it's a math problem. Problem conditions: Shakti needs to kill 30 regular Dwarves in one hit (he is in a max-level Dwarf Cottage). The question is: how many Troglodytes does Shakti need for this at level 1; Shakti at level 3 with Expert Attack and 4-2 skills; Shakti at level 5 with Expert Attack, 4-2-1-3 (30) skills, and with Blessing in the spell book. I hope this isn't too complicated...
