This is the most important tip I can give you, considering the majority of your time in FFXVI will be spent wailing on enemies. And though it’s obvious – like yes, duh, extend your combos in an action game – what’s not apparent are the simple ways you can do that. First, unlock everything you can in Clive’s starting ability circle. This unlocks moves like down thrust, lunge, an ability to jump off enemies, and more. These moves work together to extend your combos greatly.
For example, I always close the distance to an enemy with Clive’s Phoenix shift ability, lunge at them, hit them a few times, and then hold Square to imbue Clive’s sword with fire, launching them into the air once you strike. With them airborne, I can now wail on them in the air, use a couple of abilities, like Garuda’s Gouge, and then I can press Square + Cross to perform a downward thrust, which slams them into the ground. If they’re still alive, a few more hits might take them out or, if they’re a more challenging enemy, at least staggered, which opens them up to even more combos. You’ll find a rhythm that works for you, but the bottom line is when in combat, your focus should be on extended combos to maximize damage.
