Hey,

I've got a new hexblade character sheet started but i dont seem to have the box to allow a glaive to be a hex weapon, I can do so with other weapons but not the glaive as i want, any ideas?

You can't apply Hex Weapon to two-handed weapons - unless it's also your Pact weapon from Pact of the Blade.

Whenever you finish a long rest, you can touch one weapon that you are proficient with and that lacks the two-handed property. When you attack with that weapon, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls. This benefit lasts until you finish a long rest. If you later gain the Pact of the Blade feature, this benefit extends to every pact weapon you conjure with that feature, no matter the weapon’s type.

too busy theoretically building the later levels of the class to remember that, thankyou
