I use the strongest glaive, charge it to its max, and slash as many enemies in one go as i can. Also, doing an aerial attack with a glaive (on either main or secondary weapon) is always a good way to go.
The only time i really use brush techniques is when i have to Power Slach a sheild of some kind, when i have to deal withe the elemental wheels/mirrors, and when i use Veil of Mist to slow the Dogu.

When it comes to the proliferation of Evil Raos, Wakas and Nagis at the end of the final challenge, i usually just use a Vengeance slip, then when it wears of, i usually have full god-hood. I then wait for that to be used up, then use another vengeance slip.

I just do what I always do against enemies. Nothing special since it takes an effort to actually die in this game.

rely tie with all your hp but i used 3 hp 3 ink pots and the first 2 beginning weps alone nothing more my tactic was to keep hitting at the right time and used my lighting when possible and blizzard lets see anyone do it that way and say its easy i bet after u try my way of playing the game i bet ull change ur mind in saying its easy after all that hard work
