This is how I would level up (did 1 yesterday in 8 hours) (also get the level up and cookies chest at lvl 50)
*Make sure you are using 8x tome, cookies, new savior exp, pet exp buff (if you can get spout and statue get those too)
Use the free token they give you.
1-50: grind tenant garden ( use Blessing buff )
50-100: level 50 dungeon (reset dungeon if needed)
100-120: Do mission only
120-170: lvl 120 dungeon and mission
170-180: only mission
180-230: 180 dungeon and mission (you can start using multiplier here on Dungeon only!)
230 - 270: Do 230 dungeon only and use multiplier (should be 260 in 2 runs)
270-300: do the 270 dungeon use multiplier
300-330: do 300 dungeon and use all multiplier + resets you can.
you should of made around 5 mil in silver, and be 330-340 by the end.
