Tips for using these new actions
- Heart of Corundum is your new go-to defensive cooldown at level 82. It's great for mitigating damage on yourself or a party member, and the added effects of Clarity of Corundum and Catharsis of Corundum provide extra survivability and a nice little heal when things get dicey. Remember, the Brutal Shell synergy is key!
- Hypervelocity at level 86 is a quick, instant-cast attack that you can only use when you have Ready to Blast. It's a nice little damage boost, but keep in mind you can't put it on your hotbar, so be ready to use it when the opportunity arises.
- Finally, at level 90, you get Double Down! This is a powerful AoE attack that costs two cartridges. It hits hard, especially the first target, and then reduces damage on subsequent enemies. Since it has its own 60s recast, you'll want to weave it in strategically for maximum impact, especially during burst phases.
