To get the Sick Burn achievement in Halo Infinite, you need to kill an enemy player with a fully charged shot with the Ravager. The Ravager is a powerful weapon that fires three bursts of plasma per shot. The fully charged plasma explosion also causes an area of ​​effect that looks like bright red fire.
To get this achievement, the Ravager must be fully charged by holding RT on Xbox or left-clicking on PC. You can tell when it's fully charged by the flashing red indicator on either side of the reticle. A fully charged shot is capable of killing an enemy, but only if they also take the area of ​​effect damage.

The easiest way to accomplish this achievement is to use uncharged shots with the Ravager or another weapon to break the shield, then fully charge a shot and launch it at them. Ravager's shots travel in an arc, so it can be difficult to line up shots from afar.
The Ravager fires slowly compared to many weapons, so achieving one-on-one success can be difficult. Firing the full charge shot near an enemy behind an enemy who is already fighting is a good way to trap them by causing them to take too much AOE damage if they retreat with a broken shield.
