Gear by world

Weapons are sword-type items; armor comes in sets of four. Toughness is spread evenly over the four pieces, and the bonus health is split 15% helmet, 40% chestplate, 30% leggings, 15% boots (rounded).

World	Weapon damage	Armor per piece (H / C / L / B)	Armor total	Toughness total	Bonus health	Tool tier
World 1	7	3 / 6 / 4 / 3	16	1	0	iron
World 2	9	3 / 6 / 5 / 3	17	2	0	iron
World 3	11	3 / 7 / 5 / 3	18	3	2	iron
World 4	13	3 / 7 / 6 / 3	19	4	4	iron
World 5	16	4 / 8 / 5 / 3	20	6	6	netherite
World 6	19	4 / 8 / 6 / 4	22	8	8	netherite
World 7	23	4 / 9 / 7 / 4	24	10	12	netherite
World 8	28	5 / 10 / 7 / 4	26	12	16	netherite
World 9	33	5 / 11 / 8 / 4	28	14	20	netherite
World 10	40	5 / 11 / 9 / 5	30	16	24	netherite

Weapons need 8 of the world's base resource and a stick; a full armor set needs 24 (5 + 8 + 7 + 4). World 7 is the exception: the Diving suit has no helmet (the head slot belongs to the snorkel helmets) and is made of Abyssal Cobalt. The Spore Vat has a second sword recipe that uses 8 Sporite and 1 Roots.
