Artificer becomes a construct wrangler

This is using Eberron Forge of Artificer rules:

My artificer, and everyone in the party quickly filled all their attunement slots. This meant that my Magic Item Replication feature had to focue on items that dont require attunment.

At level 5 this meant using level 2 spell Summon Homunculus, which has a built in force attack weapon that works in melee and at range that does 1d6 force dmg.

At level 6 this meant a Flying Wonder (Forgotten Realms: Adventures in Faerûn) and arming it with a wand of magic missile, also from plans.

At level 11, build a spell storing item with Lightning Bolt in it and give it to Homunculus.  If you play an artillerist, then use Fireball instead.

At level 14, this meant adding plans for Stone of Controlling Earth Elementals and also the Horn of Valhalla (Brass) normally the horn can only be used once a week, but after a long rest, you can rebuild 2 magic items, and basically get a brand new horn.

You have your built in artificer attacks.

Homunculus attacks (1s6) and at level 11, wit spell storing item and 10 lightning beams

Flying wonder with wand of magic missiles ( 7 vharges)

At level 14,

one earth elemental that lasts for.1 hour

Three Berserkers that last for 1 hour.

What did you use attunement slots on?
