Talus is a champion with high burst damage and excels in a 1v1 against any unsuspecting enemy backlines. However he is vulnerable to any types of CC whether it is stuns, slows or cripples. If you are hit by these, then you're in deep trouble.
Talus can do a lot of damage in a 1 vs 1 but his health relatively low. Travel is groups of two or more if possible and necessary. You can force him to use his Rune of Travel early and cut unnecessary damage from you or your team by focusing him.
