SAM positional requirements?

[Tufelhunden]

Some tryhard sam take physical dmg on purpose so their defensive skill triggers a genki skill which consumes less of the gauge than the one without the trigger, its a very small potency increase. They can do it every 15s, they gain like 18potency or something.

Thanks. Problem was it was Inferno and he was snacking me hard through cool downs then the healer was struggling. But at least I know now. Again thanks for the information.
