Claude

In teamfights, Claude should use his 1st Skill to stack up his buff first, and look for the best opportunities to get close to enemies with his 2nd Skill, and then use his Ultimate to finish them off.

In the laning phase, Claude can use his 1st Skill to poke the enemy, and use his 2nd Skill to close in on them when their HP is low, then use his Ultimate to kill them.
