So, just spent 15+ minutes(I don't know if I'm either Really lucky or the cool down in-between taming boars is a lot less than cows) taming my first pig. And after asking some questions,
I had to bring the sucker some ways(him attacking me all the way) till I got to shallow water, which took the bulk amount of my time this morning.
So what I propose is that quell now takes 20 coins each time you use it.(as well as battle intensity has to be 2 or lower) there is no interruption in combat and you still cannot attack the animal.
now every time you use quell there is a 1% chance you tame said creature. And every subsequent time you use quell you get your odds increased by 5%. IE: 1st attempt 1%, second attempt 6%, third attempt 11%, fourth attempt 16% and so on and so on, so by the 11th time your at over 50% chance of totally taming said beast.
anyway hope you like it, if you can improve it, by all means please reply.
