Broke through 35 with a hidden quest, got up to 20k gems!

Finished them all haha, got some nice rewards. I thought 50k gems was the max for breaking through level 30, but getting up to 20k gems for breaking through level 35 made me play hard. Personally, I favored skills that increase attack range and perform area attacks. I use a rifle for fast attacks, but when ambushed, I felt that a rifle alone was not enough. Skill that attacks all enemies within range after reload. Skill that increases attack range and performs area attacks. Then, for the final skill tree, I go for the one that makes the magazine -999, so I shoot one round and reload. This way, every shot becomes an area attack, which is great. Adding freeze > after reload, up to 3 ice arrows is also good. Since the attack range increases, I can deal with boss monsters from a bit further away, which is convenient.
