Wizard's mind bomb

The Wizard's Mind Bomb is a drink which aids your magical powers, though it seriously addles your melee combat skills. It is sold at the Rising sun bar, Falador.

Effects

 * Increases magic level by 3 for around 30 seconds
 * Lowers attack by 4
 * Lowers strength and defence by 3

The reduction in your other skills takes longer to recover than the increase in magic.

Conclusion
Never rely on this to cast your main combat spell, though using one in combat can enable you to open with something more powerful, and get more hits until it wears off. Losing 3 defence level is only a problem if your target is able to retaliate.

It is more useful to enable the use of non-combat spells at 3 levels earlier than otherwise possible, great for jewelry enchantment or High Alchemy, though unless you are very quick, the number of items you can process on a single drink will be quite low.
