I'm astonished to see people having so much trouble with ONE fight, if you really wanna beat t5, just read about it , train and beat it.

Theres NOTHING hard now with the echo buff, you need only to focus on the dive bomb and the twister phase, thats all there is to it. Thats like... 4 minutes in the whole fight and the dps check is now unimportant.

Heres how you do it: on divebomb, stay in the pit, go out when you see green mark and go back in right away. Three Times
wack on monsters for 45 seconds, repeat divebomb dodge.
Kill all snakes, you now have around 20 seconds to heal and go stand on nodes.
now Twister phase, focus Twintania and spread out, when you see her casting twister stop all your actions and move. Kill Dreadknights as they come (should be 4 tops) while keeping an eye on Twintania's Twister.
Now just burn her, tank should be ok on hatch.

Can't do these 6 steps? Try again
