Ok.There is a big point: the pet needs to fight against real monsters and not against harmless trainers, so my question is how much stamina is needed to keep "firing" abilities like acid rain or trial by fire at max rate? Look here for bio pet abilities. https://www.uoex.net/forum/viewtop...

Yeah that would be an interesting test, can`t afford it though. I think the damage will grow it is just that her unarmed attacks seem to have higher than 14-17 of my axe. With 19-22 bow bio starts to deal more damage than barehanded and therefore leeches more stamina. Elven bow seems to be best weap...

To clarify: one has to get a bow with Quiver property and an enchanted elven arrow in their backpack, double tap the bow and target an arrow. Then equip the bow onto bio - you got your bio Hit Lightning: 100% for free :) Arrows cost ~80k per 500 in Heartwood, if people are interested I can sell them...
