He's not. If he were to get the buff dispelled or it simply runs out, he'll need to find a Soul Linker to have it get re-cast. Even if he dual-clients he'd either have to get the Linker to always follow him, or always worry about the chance of his equipment suddenly being unequipable...
...Yeah, no.
SO ...I'm assuming MemoZzz is on a private server, using eAthena.
One link is all they need to wear the headgear or weapon forever, 'cause eAthena hasn't scripted that "change-screen-unequip-thing" yet, or probably can't. A Dual clienting slave that follows him everywhere isn't necessary; just log in and out when you need it whenever you feel to change headgears or spam for the +10 to all stats. ...Besides, if you're fighting someone who's got the ability to disarm or de-equip your armours, you're not going to win in the first place, unless it's the gunslinger class or someone with a card.
Having no equips just rape you hard,
especially when you're an instant-cast.
If this is an official server, then that rocker on the armour is the way to go, although binoculars are still a nice option: un-equipable, unbreakable. ..You're still screwed in the long-run, though. Official servers still hate Super Novices.
Edit: Making a Super Novice without links and instant-cast is just..eugh...bull****.
