When terminus uses his ult to get back alive, use reversal. If you time this ability right, you can fire over 3000 damage towards terminus and let your teammates or yourself finish him off.
Escaping Tyra is very difficult, since she can reveal you easily and spray you down. Always have your impaler arrow ready and force her in front of walls. Once she's pinned, she has no ability to escape your rain of arrows (planted).
