Unstoppable

When to use it

Rated above the flat physical-damage node in the same cluster, because getting into range at all is the harder problem. A second source described this node as a short damage amp of roughly 5% and rated it poorly; the tooltip does not support that reading, so the damage claim has been dropped rather than presented as a disagreement. This is a defensive node.

Builds using this

• Shadowstrix — dual blades, wound explosion — Master Deemo explains it at 15:00
  Super armour, to contest other super armour and to stop pokes being interrupted. He has seen the build run without it and says the pokes get much weaker.
• Shadowstrix bait-and-stun — Swanifier explains it at 02:30
  Taken for want of a better option in the row. The creator recalls it as a short ~5% damage window; the in-game tooltip says it grants Super Armor on Spinning Slash, and the tooltip is what the record carries.
