Chapter 3 mountain refuge

[AnemoiZ]

Love the game! Bought it on switch and near 100% in 6 hours. However i can't for the life of me figure out how to clear Chapter 3's mountain refuge level within the round limit, even with max upgrades. Would appreciate if anyone can give a hint or two

Hints:
- At least one Stranger's not gonna make it.
- Exploding Arrow, Smoke Cloud, Force, and Vault will be necessary.
- The Stranger in the upper-left is dealt with last.

Full Solution:
Round 1:
1. Left
2. Up
3. Left
4. Left
5. Right
6. Exploding Arrow Up

Thanks! I figured out an alternative method using your hints, no Force needed but with a slightly messier execution.

Round 1: Same
Round 2: Up -> Smoke Cloud -> Left -> Vault 2 down 1 left (lowest landable tile) -> Left (End on 5th turn, so a beast dies to fire)
Round 3: Left -> Left -> Wait -> Push left -> Left -> Exploding arrow Up
Round 4: Push right -> Up -> Up -> Vault to tile below stranger -> Up (Can end here, last beast will die to fire)
