Question about Alexander Prime fight.

[Zarchery]

I did this fight recently on a lark, just to see if I could solo it. I did, and got the pact with Alexander. So if I ever bother to level Summoner further than 30, I'll be able to summon Alexander.

A friend of mine is actually levelling Summoner and I told him I'd do this for him. Now I know that there's some repeatable quest that's completely identical that comes after this, and to do that I would have to farm 3 more Plumbago ores. My question is; since I already did the Alexander prime quest (Waking the Colossus), would I be able to do it again to assist my friend, without doing anything else? Or would I have to do the follow up quest Divine Interference, which would mean getting 3 more Plumbago ores?

Instead of posting here, just go to wiki and you'll see the next quest and it's requirements for redoing it (like all prime avatar fights).

You're right. I was overthinking this. If I wanted to assist on Shiva, I'd still need a new Tuning fork of Ice, so Alexander wouldn't be any different.
