Dungeon Defenders - checkpoint 3 solo with 4 splits

I am playing a range gunwitch, which is strong solo. This character doesn't need hdmg because it doesn't scale the icy needle damage. Icy needle damage cannot be scaled with a cat either, so I use a navi for more survivability. Gunwitch stats: 7960 trange 3881 hhp 2975 thp 2731 trate
