Only significant items are detailed here; others are merely used to build other things, or are explained already on the Game Hints
Allows you to equip three Buster Parts at once rather than two, although Roll doesn’t bother to tell you this when she makes it, which she did in the first game.
I’ve been told that these protect against getting the “burning” status ailment after walking on lava or ice floors. Probably the reason I never noticed this is because I already had items in my inventory that prevented such special damages, and thus the lack of them was not something that caught my attention. If you find yourself in the same situation, don’t bother with these shoes.
These prevent you from sliding on icy surfaces.
Refills your life meter. You can purchase extra packs from the Junk Store, and refill used packs there as well. Each pack restores one unit of energy when you use the canteen. A nice feature is that the canteen will not refill more than you need; any extra units remain in the canteen for future use. This is unlike Mega Man games where Energy/Sub-Tanks are used completely even if you don’t need all of their energy.
This helps prevent MegaMan from being knocked down by attacks. (No, I don’t know how wearing a helmet protects you from being knocked over. Just roll with it. Pun intended.)
When you are wearing these, you can walk across electrified floors without harm.
These shoes allow you to roller-dash while underwater.
Equip, then hold
to Roller Dash. This allows you to travel faster and can be entertaining as well. If you jet off the edge of a ledge or other object, MegaMan will jump automatically; otherwise there is no way to jump while dashing. Control MegaMan with the control pad; press forward to go faster and back to slow down.
Whenever MegaMan takes damage, if there is a possibility of him being attacked again in rapid succession he automatically attempts to roll out of the way of the second attack. Generally this is helpful; however, don’t wear this in tight quarters where MegaMan is likely to roll himself off a ledge and onto, say, lava.
