Lesson 6: Grenades
Grenades is a term that I use for any once per battle weapon. These weaons are just what they say, items that may only used once per battle. Some of these items when used will vanish forever. Weapons in this family include Snowballs, Snowflakes, Exploding Pizza Pasty, and Clockwork Grundos to name but a few. Another class of these items are persistent, that is they may only be used once per battle, but you get them back when the battle is over. Weapons in this family include Mud Mixture, Illusens Earth Potion, Honey Potion, and Battle Potato to name only a few.
Grenades commonly carry higher damage output than their equivalently priced multi-use counterparts, hence their popularity. The drawback to this high damage, other than the once per battle restriction, also tends to be the restriction of these types of weapons to only one per pet and the attacks are generally composed of only one or two types of easy to block icons.
What all of this essentially means is that grenades, in the absence of higher damage output multi-use weapons, are extremely popular, and reasonably so, for use in attacks that will be unblocked; in fact they are usually not effective at all if used in any other situation. This does not mean they can’t be, and that there aren’t exceptions to the rule. – Jadeasahi
