In some earlier editions small characters were not allowed to use two-handed weapons. So gnomes, halflings, and dwarves couldn’t use pole arms, great swords, battle axes, heavy hammers, heavy maces, etc. This was a little odd because the battle axe is such an iconic dwarf weapon.
Is there a feat to make two-handed weapons One Handed?
Absent any special feat, class ability, or what have you, it is not generally possible to wield a two-handed weapon in one hand. You can carry one with a single hand, but not fight with it.
Is it possible to use a greatsword with one hand?
And there’s no way of using a greatsword one handed – even if it was a halflings greatsword, the halfling would simply have disadvantage for using a heavy weapon. It wouldn’t take much to redo weapon sizes to account for this. Every weapon has a size: tiny, small, medium, large, huge.
Is it possible to one hand a greatsword?
Can a creature hold a two handed weapon in one hand?
While it doesn’t state that the now larger creature can hold a two-handed weapon in one hand, it does give extra damage for the extra large weapon. The text suggests that it is the extra size of the weapon that deals the additional 1d4, and not that it is an extra large creature wielding it.
Which is bigger a two handed weapon or a one handed weapon?
Size would make the bigger difference however. A larger creature could likely use a two handed weapon because they have the larger forearms and hands to support the different leverage and compensate the balance, essentially making it a one handed weapon relative to their size.
Is there a limit to two handed weapons?
As always, a DM can rule how they’d like, but it is fairly clear that the two-handed property limitation is not based on creature size, but on weapon property requirements. What matters is having both a larger creature AND a larger weapon for there to be an increase in damage or abilities. Why just one-handed?
Can a small creature wield a heavy weapon?
Pg 147 of the PHB: small creatures have disadvantage on attack rolls with heavy weapons (however my group has been known to hand waive this in the case of gnome barbarians because, gnome barbarian) Along with the rule from the PHB, there is another option.
