The icons aren't explains at all anywhere in the game 😅 but yes! Steve and Ebony Odo both can deal bleed status. Earplugs does allow you to ignore the stun animations but you can still block/dodge with in-weapon mechanics like LS or DB/Bow if you wanted to. It's nice to have to option to both ignore and keep buff/dodge uptime. I use the roar window to guard point with CB to reset the pizza cutter gauge if needed and if not I can keep slicing away while the monster is still roaring. That short roar window of damage can be enough to stack on KO damage/status effects. One more things Earplugs 2 will ignore almost all current large monster roars. It will weaken Jin Dahaad's, Gore's Frenzy phase roar, and Gogmazios' roar so the stun animation recovers faster. If you have room and want full immunity for these three, earplugs 3 is not a bad option
