now, how many angers per wave with what kind of gems will this require? Start with G23 and maxed gembombing skill. Then, calculate the end HP and armor, then think a bit.
meh. Angering by grade higher than 31 (=100% hp increase) gives worse results. Monster's amount grow more slowly than hp. 15 angers by 32 grade gives more hp than 16 angers by 31, and less monsters .
anyway, how many monsters does a single G31 give to a wave, with maxed gembombing skill? In order to summon 100k monsters per wave, one needs to summon (100k/this number) times, this will make HP of monsters be (initial)*2^(times), and armor (initial)*1.25^(times). Also one cannot summon 100k for the first ~15 waves (depending on skills), so further ~50 waves would need to be summoned ~1.5 times more. I wonder what decimal power will be those numbers, I estimate HP to be in range of 1e100 and armor in range of 1e30.
