Dauntless Machete

Weapon (shortsword), rare (requires attunement)

Although the handle of this +1 shortsword is well worn, its blade still appears as sharp as the day it way forged, and the whole piece is stained a sickly green. While you hold the dauntless machete, you move through naturally occurring difficult terrain (such as undergrowth, loose sand, or slippery ice) at normal speed and without taking damage or suffering any other impairment. In addition, as an action you can move one-half your speed through naturally occurring difficult terrain, converting it into cleared terrain rather than difficult terrain for 1 minute, after which the squares return to their previous state. If the terrain is magically manipulated, such as with entangle, plant growth, or wall of thorns, you can clear one 5-foot square as an action, and do not take damage or risk becoming grappled, restrained, or otherwise impaired while doing so. Additionally, when using the dauntless machete to attack beasts, you have advantage to your attack rolls.

Epic Attunement. You have advantage on attack rolls with the dauntless machete against plant creatures, and as a bonus action when you hit a plant creature you can deal an extra 4d6 slashing damage. You cannot use this bonus action again until you complete a long rest. Finally, you may spend an action hacking away at any plant or vegetation affected by a non-instantaneous plant-affecting spell, 5 affecting it as dispel magic cast as a 3rd-level spell and using your Strength score as your spellcasting ability score where applicable.
