One incredibly angry Cat wants to come and politely tear the opponents to shreds.
you can easily maintain the 2 giving you 123%^ armor and attack speed, activate the roar whenever it is convenient and use the 4 to re-heal and deal with any frustrating enemies or clumps of enemies.
I have tested this well into the 60min+ steel path survival maps and it tears clear lines through enemies. I hope you enjoy :)
Note: if you prefer not to use a second umbral forma, [Adaptation] works in place of [Umbral Fiber] since we already have a large amount of armor.
