# Gizmo
Gizmos are a group of new monsters in dNetHack that use the G symbol but are not gnomes[1].  Using farlook on a monster with this symbol will reveal that it belongs to the monster class "gnome or gizmo".
Although they differ widely in their characteristics and attacks, gizmos share the common trait that they are nonliving machines.  As a result they do not need to eat or breathe, and they are not affected by poison, petrification, disease, or death magic.  Many resist level drain as well.  On the other hand, they do not naturally regenerate health.

Clockwork soldiers are created by tinker gnomes through their tinker attack.  They proceed in predominately straight lines, attacking anything that gets in front of them.  With each step, a clockwork soldier has a small chance of changing its course of travel incrementally to the left or right at random.  A clockwork soldier will therefore spend much of its time stuck in corners.

Clockwork dwarves are created by tinker gnomes through their tinker attack.  Like clockwork soldiers, they proceed in predominately straight lines, attacking anything that gets in front of them.  Unlike a soldier, clockwork dwarves can dig, and will therefore spend much of their time stuck at the edge of the map or veering drunkenly back and forth excavating the current dungeon level.

Faberge spheres are created by tinker gnomes through their tinker attack, moving in predominately straight lines like clockwork soldiers and dwarves.  As with clockwork soldiers, they have a tendency to get stuck in corners.
Faberge spheres are the gizmo equivalent of regular spheres: they explode when destroyed, or when they self-destruct to cause damage to a target.  Their explosion is a little less damaging than an e-type sphere's (3d6 damage rather than 4d6), but the damage is physical rather than energy-based (fire, cold, shock, etc.), so it cannot be resisted by energy resistance.  They are faster than ordinary spheres (16 instead of 13) but have a lower base level, so they give less experience when destroyed.

Firework carts are created by tinker gnomes through their tinker attack, moving in predominately straight lines like clockwork soldiers and dwarves.  As with clockwork soldiers, they have a tendency to get stuck in corners.  A firework cart explodes in a large display  of multicolored blasts when killed or when it strikes a monster.

Juggernauts proceed in predominately straight lines, attacking anything that gets in front of them and digging through any walls in their way, much like a clockwork dwarf.  
When on the level, a message is shown: "You hear (loud) scraping (in the distance)."  They share this message with their brethren, Id Juggernauts (see below) 
However, Juggernauts will home in on the character, adjusting their vector of travel to move towards them.  In addition, Juggernauts can attack into the two directions neighboring their direction of travel, as shown below:

..x   ...
.GX   .Gx
..x   .xX

X=direction of travel
x=squares into which the Juggernaut can attack.

They can be generated in dNetHack vaults.
