Scorching Cleaver

You gain a +1 bonus to attack and damage rolls made with this magic weapon. This battleaxe has 8 charges and regains 1d6 + 2 expended charges each day at dawn. As long as the weapon has at least 1 charge, attacks you make with it deal an extra 1d6 fire damage to any target it hits. When you roll a 20 on an attack roll made with this weapon, it regains 3 expended charges.

Erupting Slash. As an action, you can expend 3 or more of the battleaxe’s charges to slash the air in front you. When you do, a line of fire 30 feet long and 5 feet wide erupts from the blade. Creatures within the line must succeed on a Dexterity saving throw or take 1d6 fire damage for each expended charge. If you expend 4 or more charges in this way and leave the battleaxe with 0 remaining charges, the weapon overheats. When it overheats, targets within the line take an extra 3d6 fire damage, and creatures that succeed on the Dexterity saving throw take half damage instead of avoiding the effect. The DC for this property’s saving throw is equal to 8 + your proficiency bonus + the number of charges you expend.
