Bombs. Nuff said.
Alrightalright. I had a couple of issues killing Liadri with my nade build, as it’s a little difficult to focus constant AoE targeting AND to keep your camera moving around (to keep an eye on the kitten rift and the death bombs). That was literally my issue, observation.
I swapped over to my bomb kit, increased the radius, made sure I had power shoes on (25% speed, didn’t even need a swiftness trait with this on) and backpack regenerator (permanent health regen while in kit). All of a sudden, no issues. I was able to keep an eye on the entire battle-field with ease. I spotted rifts as soon as they formed, I could keep an eye on the death-bombs, and anticipating the AoE circles was incredibly easy.
I was even wearing my WvW PVT armour, since Liadri actually dies very quickly. I allowed her to chase me around while her attacks whittled pathetically at my 26k hp and 3k armour, and she died in a surprisingly speedy time (I do have high power which makes bomb-training very painful).
I beat her the first time I swapped to my bomb build. Really amazed me just how simple it made the fight.
