If the Warp system gives you another Gepard, you can use this duplicate to upgrade Gepard's Eidolon level (up to six times). Technique: After Gepard uses his Technique, when the next battle begins, a Shield will be applied to all allies, absorbing DMG equal to 24% of Gepard's DEF plus 150 for 2 turn(s).

This effect can only trigger once per battle.

Talent: When struck with a killing blow, instead of becoming knocked down, Gepard's HP immediately restores to 25% of his Max HP.

Ultimate: Applies a Shield to all allies, absorbing DMG equal to 30% of Gepard's DEF plus 150 for 3 turn(s).

Skill: Deals Ice DMG equal to 100% of Gepard's ATK to a single enemy, with a 65% base chance to Freeze the enemy for 1 turn(s).While Frozen, the enemy cannot take action and will take Additional Ice DMG equal to 30% of Gepard's ATK at the beginning of each turn.

Basic ATK: Deals Ice DMG equal to 50% of Gepard's ATK to a single enemy.

Aside from that, you're going to mostly play him like a normal DPS. You can also just cast the ultimate during hectic parts of the fight and save it if you don't have to. Due to the 'problem' stated above, a little Energy Regeneration Rate won't hurt just to make sure you always have it whenever needed.
