Weapons and Tools - Leiriad/-Neoforge-1.20.1-Inventorium GitHub Wiki
In this modpack, the axe can be used as a weapon, so if you prefer, you don't have to carry around a sword. See Axes Are Weapons. Thanks to the mod Tree Harvester, crouching when hitting the lowest log of a tree allows you to chop a whole tree.
If you equip a hoe, you can harvest your crops with a right-click without uprooting them (mod Right Click Harvest).
If you prefer to fight with two weapons, that's possible with Better Combat. Just replace your shield with a weapon of your choice.
