User blog comment:OromisMasta/Custom Champion - Khreox, The Banished Shaman/@comment-1330314-20140520031222

I've always loved the idea of a shaman in League. Your concept has a lot of features I'd like to see in a shaman-type champion, and a lot of original ideas. I also think that there are some features of your kit that can be streamlined a little.

Although it may not look like it, Ritual of Blood is a slightly more painful version of 's Ferocity. Although the health cost mechanic is thematically great and interesting in terms of gameplay, the fact that you can't truly control it (waiting until the duration ends means you effectively silence yourself for 7 seconds) means it ends up creating a serious gameplay issue. Additionally, you may not want to enhance the first ability you cast while entranced. A simple solution to avoid this would be to allow Khreox to charge his spells while entranced: charging the desired spell for a short duration would enhance it and incur the health cost, but simply casting it would throw down the basic version, allowing you to decide which spell (if any) you want to augment.

Sacrifice is a nice, simple spell, with a cool interaction with Ritual of Blood. This looks great.

Tribal Totem is a great area control tool that can set up great plays. I would advise giving Khreox a means of detonating the totem early (with a second cast, perhaps?), as 3 seconds is more than enough time for anyone to escape from the totem's AoE, and therefore from its root/stun.

Cursed Mark is good for synergizing with his other abilities, but can easily be streamlined to increase the damage taken by the victim for the duration of the mark. I also think the Ritual healing should only activate if you kill the target, or at least at the end of the mark's duration (something along the lines of "once the mark disappears, you heal for a percentage of the increased damage taken by the target"), since Tribal Totem already has the potential to provide more immediately available healing.

Zealous Trance is thematically awesome, and can provide some great sustain-based gameplay. I would advise you to be very careful with an ultimate like this, because if done wrong it has the potential to become extremely binary: either you take more damage than you can heal, so you can't use this for very long, or you heal all of the damage you take, and so can stay for as long as you want in Zealous Trance.

In summary, you have an awesome kit set out for a sustain-based tanky mage. It's also very hard to do a kit with a theme like that, considering can become incredibly hard to kill while dealing massive damage. You need to focus on a kit that should always make your champion somewhat vulnerable, no matter how powerful his healing becomes.
