Squire-only solo Insane HC build for Alchemical Laboratory.

No bought/traded items, self-found only.  Didn't have any set bonus on my armor when I did this.  All level up points go into hero speed.

I was level 34 when I completed this.  I strongly recommend that you be at least level 34.  Level 34 allows you to equip Epic-quality items, and more importantly, gives you 700 max mana which lets you upgrade your defenses to level 4 (1-star).

I also recommend that you level up your generic & fire resist on your armor, as well as upgrading the base damage on your weapon.  The resists will prevent you from getting one-shot by the boss.  The base damage on weapon will allow you to kill the lightning coils as fast as possible (make sure you turn on blood rage when attacking the coils).

Always keep the boss in your field of vision, so that you can run away if he flies over to hit you.

• The back blockades (the 2 on the left) only need to be level 1. 
• The front blockades (the 2 on the right) should be at least level 3 by the last 2 waves.  Most of the enemes come through these 2 chokepoints.
• Make sure to upgrade all harpoons as much as possible.  You should have enough mana to get almost all of them to level 4.
• When the boss gets stunned, make sure to turn on blood rage while you are attacking him.
