What do you like capturing with Beastmaster?
1. Great Wolf - Buffs your entire army with +1 attack per level of the wolf, and it starts at level six.
2. Big Bears - Maul em baby!
3. Umberdroth - Overpower!
4. BIG Spiders - Web, Poison
5. Really big Rock Spiders - Tank and Spit Poison
6. Skaths - x3 dmg Bite
?. Anyone try Nagas?
Note you can only capture BEASTS. Dragons such as Slags etc cannot be tamed. Ophidians, as beasts, still cannot be captured as they are magic immune.
Tactic from Chibiabos - "It is very helpful to have or bring along a spellcaster who can cast Haste if you want to capture more than one critter in one tactical battle, as the cooldown for Tame is 10 turns ... that's a big reason why webcasters are helpful, even beyond the first one you capture, to help keep the other critters you want to tame from melee attacking."
