It really depends... Skilled Champ against Skilled Cross i can't say who might win. Champ can always Asura (cowards way?) if things aren't going well, but Cross can easily avoid that (Backslide + Hide or simply hide if not ruwach casted) and 1 shot KO him. Champs also can try Finger Offensive, but Cross can also vvoid that (if can hide before casting ends). The worst case is if Champ has no cast time, there cross has serious problems. Cross has Cloaking, and if Champs doesn't has neither Maya Purple or Box of Sunlight, must find him quickly before Sinx can 1 shot KO easily. Really, who will win depends on:
- Equip (reductions, flee, etc).
- Builds (in order to win, Cross must be 1 shot KO type build and Champ must be a fast caster, the faster the better).
- Tactis (NOT SKILLS, TACTICS, we suppose both are Skilled but has differents tactics, I mean how each one acts).
