Getting Started with Better Combat

There is nothing to craft or unlock - the new combat applies to the melee weapons you already use.

1. Hold any melee weapon in your main hand (a sword, axe, or any modded melee weapon).
2. Left-click to attack. Instead of a single poke, your character performs a full swing that arcs through the space in front of you.
3. Aim at a group. Any enemy inside the swing's arc is hit by the same strike, so line up multiple mobs and clear them at once.
4. Watch the crosshair. The attack indicator shows when your swing is charged and highlights the enemies about to be hit - time your clicks with it instead of spamming.

That's the whole loop: hold a weapon, swing into the enemies, and let the sweeping attacks do the work.
