Nix is a great dragon if you want to breed a bunch of dragons easily. Not so great a dragon if you actually want to rip through a base. The problem (as always) is simply that you just can’t pump out enough damage on well organised and defended bases. Fireball is too expensive to use, Elemental Mayhem too situational, which leaves Globe of Invincibility as your best spell.
Cannon Resist is useful, but we really advice that you leave Nix alone and concentrate your efforts elsewhere.

Enki and Elixis will get Nix (as well as Urd and Ettin) for 28k tokens, or if you want to wait you can get Nix as you are breeding for Khrysos.
