This dnd 5e feat is available in Unearthed Arcana 15 – Feats.
Even though the spear is the simple weapon to learn, it actually, rewards you for a particular time which you’ve been taken to master it. With this spear mastery 5e feat you can gain the below mentioned benefits:
- You can gain a +1 bonus to attack rolls that you make with a spear.
- Whenever you use a spear, then it is damage dice that changes from the d6 to d8, also from a d8 to a d10 whenever it wielded by two hands. (Basically, this benefit has no effect when if another feature has already been improved a weapon’s die.)
- Anyway you can easily set your spear in order to receive the charge. Like a bonus action, you can select a creature that you could see which is at least 20 feet away from you. But if that specific creature moves within your spear’s reach upon its next turn, you could easily make the melee attack which is against to it with your spear like a reaction. But if an attack hits, the target shall take an extra 1d8 piercing damage, or else an extra 1d10 piercing damage if you shall wield a spear by it’s two hands. You can not even use this ability if a creature used the Disengage action before it’s moving.
- Like a bonus action on your turn, you are able to enhance your reach by a spear by 5 feet for the rest of your turn.
