Grinding is when you fight monsters for Taros, Fusion Matter, Nano items (Battle booster of Nano Potions), or a specific item. It is best you use Scavenge, Run, or Heal Nanos, to your advantage.

• Scavenge-Scavenge nanos are giving you more Fusion Matter while Grinding.

• Run-If you use a run nano it is an option to get to monsters faster.

• Heal-When you grind it is good to have a Heal Nano; it allows you to keep going without stopping to rest.
• Sneak- Prevents other monsters from seeing you while in combat.
• Sleep or Stun- Keeps the enemies incapitated for a while (allows you to focus on one enemy while the others are snoozing/dizzy.)
• Damage or Drain- deals additional damage to your foes.
• Tips: *Use Shatterguns, it allows you to deal damage to more than one monster at a time;
• Feed Gumballs to your Nanos.

There are five best places to grind.They're from lvl 31 to lvl 35. These places are:

• Huntor's Crest - From Demongo to the Dark Gate, (You must defeat Skull Bashers.)

• Hero's Hollow - When you enter in Hero's Hollow (From Huntor's Crest) you go to your left,then you fight the Shellworms.

• Hero's Hollow - Around Cheese, (Eyebulbs territory.)

• The Precipice - You go to the Resurrect 'Em.(You defeat the Great Shellworms and if you want the Great Eyebulbs.)

• Green Maw - You go around the Green Gullet.(Fight the Shellslugs.)

The Best Area to grind is in The Precipice, because in that area you can get about 2000 Fusion Matter in around 6 minutes.
