Grass Boss

The Grass Boss is the first Boss of the game, and is located at the Grasslands. It resembles a regular Grass Monster, except with glowing green eyes, being bigger, and having the ability to be invincible to attacks for a time. Once the boss loses its invincibility, it can be dealt damage. During this phase, it will stand still until it is hit, in which it will then go back to being invincible. The Grass Boss can be taken down with at most 3 hits.

How to Kill
First, you'll need to have reached Level 3, or else you can't get in it's arena.

Then, you'll have to get close to him, and start running around. Don't try attacking at this time, it just won't work.

You may notice glowing grass appearing. Once they start emitting a glow, don't touch them or it'll deal 15 damage.

Wait until he pauses. Once he pauses, attack him. This is the only way to deal damage to him without scripts.

Do this twice more, and the Grass Boss should plant his legs in the ground and start moaning. After that, you can claim a nice 180 EXP (instant level up to a beginner) and your 1st material.
