Beings of Tash Kalar

Bomb

Pattern
It resembles a stick of dynamite with a fuse. The final picture was done more round and "Imperial" style, but the pattern remained.

Effect:
It is timed. If you give it enough time (i.e., with some actions still remain after summoning the Bomb), it explodes and destroys itself and all common pieces around, regardless of color. If not (i.e., when you summon it with your last action), it just fizzles.

Strategy tips
To make the Bomb explode, you usually need to have it prepared on the previous round, so you can summon it with your first action. It may be also used as a nice comeback when you play a flare card that allows you to prepare the Bomb by placing or moving pieces or using extra actions.

Note the exploding effect does not only destroy the summoned piece, it destroys also one of the pieces used for summoning the Bomb, if common. Thus it is better if that piece is upgraded or even not yours (using improvised summoning in a deathmatch melee).

Also note: It is not necessary always to use the exploding effect. You still can destroy one common piece by summoning the Bomb and you do not lose your own piece. Sometimes, you can even benefit from the fact that it fizzles. It is an easy pattern and thus easy to fulfill "summoning" tasks. As your last action, you can safely summon it on a colored space in the midst of your tokens.

Interesting facts
Originally, this was a kamikaze goblin sapper and I supposed it would move to Highland. But Highland has enough destruction so it remained in Empire, first as a dwarf sapper, then as a sapper, and finally straightforwardly as a bomb, since Empire has several gunpowder devices anyway.

Also, originally, the Bomb exploded regardless of the timing. It was a bit annoying for the opponent, as it was too easy to set up and thus hard to prevent even if it was expected. The fizzling option added nice tactical options and made the card much more interesting.
