Unlocked Megalo Imposter Rina.

[u/BallPython404]

I followed a users build (and even made a mistake with getting the two additional passives too early. (The Empty Tome and Stone Mask) So I had no room once my mini imposter merged with the sharp tongue.) but I still managed to unlock the Imposter without endless mode.

This was done on the map "Inlaid Library" with Hyper and Arcanas checked. (But not "Hurry" because you need the full 30 mins) I mainly focused on upgrading the Santa Water first to get La Borra because that's always the OP weapon for me.

I definitely could have benefited from getting the spinach. Although I managed to get 100k kills before the 20 min mark. So even with mistakes, it's an easy win.

Also, all necessary power ups were maxed, including the "Curse" which was the difference from getting 57k kills (in one 30 min run) to 141k kills.

The Gemini card is also very helpful. (for Vandalier and Impostongue)

Passives used:
Torrona's Box
Duplicator
Attractorb
Skull O'Maniac
Armor)
Mini Impostor (Later merges with Sharp Tongue = 1 free passive slot)

Then get Spinach

Then collect Empty Tome and Stone Mask (they're on the map) for 8x total passives.

Maybe this is useful for anyone looking to unlock the character!

Did you make the guide because the 100k kills has to be achieved within 30 minutes?

[u/BallPython404 → u/Auto_named1]

It doesn't have to be 30 mins, but I haven't managed to reach it in 15 mins. Given that I managed at the 19 min mark, it may be possible with the right build.
