Diana

Diana is a 3-cost Arbiter and Challenger champion that usually plays as a frontline sustain unit. Its sustain or shielding makes it valuable when it survives long enough to buy time for the rest of the board. Diana appears in Anima Cashout lines, so keep copies when those boards are open.

Consider playing around Diana when you find a two-star copy in Stage 3 and your components already fit the unit. For items, Bloodthirster and Titan's Resolve are strong signals that Diana can stay on the board. For team direction, it fits naturally when you are already moving toward Anima Cashout. If it stays one-star, the traits do not activate, or the items point elsewhere, treat it as a transition unit instead of forcing the line.

Bloodthirster, Titan's Resolve and Guinsoo's Rageblade are recommended. Bloodthirster adds sustain and a low-health shield for extended melee fights, Titan's Resolve rewards long fights with stacking damage and durability and Guinsoo's Rageblade ramps attack speed in longer rounds. The point of the setup is to keep it alive long enough to cast and hold the frontline.

When the perfect setup is not available, use Hand Of Justice, Edge of Night, Sterak's Gage and Red Buff as substitutes. For frontline substitutes, prioritize durability, sustain, and opening damage reduction without stealing every carry item. If Diana is only a trait slot, one useful item is enough and the premium items should go to your real carry or main tank.

Early: hold useful components, but do not force the line before copies appear. Mid game: two-star Diana is the main power window for Stage 3 and Stage 4. Late game: either commit to a three-star angle or use it as a trait anchor while higher-cost units take over the items.

Place Diana in the first row on a side, or in the second row when it needs protection. It should enter combat quickly without eating every enemy attack at once. It needs time to start casting, so avoid letting it get deleted immediately.
