Part 3 of my 8th Edition Ork Codex review will take a look at the Relics and Psychic Powers available to the army.
Shiny Gubbinz (Relics)
The Orks have access to a number of useful Relics to add to the characters in the force to help them demolish the enemy even further.
Da Dead Shiny Shoota
A Kustom Shoota that is 18", Assault 12, S4, AP-1 and 1 damage.
This gets an extra 8 shots and AP-1 over a regular Kustom Shoota. This is actually pretty good, and you should be able to get a decent number of hits if hitting on a 5+ (along with the extra shots). This is a solid choice, but I don't know how often you will see it, as there are simply better Relics available.
A big Choppa that is +2S, AP-2 and 2 damage. In addition, to wound rolls of 6+ inflicts 2 mortal wounds instead of normal damage.
Again, a very solid relic to take. The chance of doing multiple mortal wounds on a 6+ is a great bonus. This is strong when added to the Monster Hunters stratagem, allowing you to do 2 mortal wounds on a 5+.
Gives the bearer a 5+ Feel no Pain type save against wounds. Cannot make a Doc's Tools roll for this model if you do so.
This is a great upgrade for your warlord, as most Ork characters struggle to get an invulnerable save. Gives them a chance of staying alive for longer. I think this is a useful Relic to take in the army.
