Kukulkan Build

Mr. Rawy,

Are you saying in general you don't know which order to buy items (and reasons why)? Let's assume so and tackle your various questions:

• What should you buy first?: the starters are meant to be purchased first, so that's probably pretty straightforward. In your 2 builds you have Pendulum of Ages and Gem of Focus, so the starters for those are Sands of Time and Conduit Gem as I assume is already known.
  
  
• Past that though, you've got some general rules for build order:
  
  - Stacking items often should be built as first main item, or at least early in the build. This typically involves magical damage items like Book of Thoth and Warlock's Staff, physical damage items like Devourer's Gauntlet and Transcendence, and protection items like Gauntlet of Thebes and Prophetic Cloak.
  
  - Items with flat pen are often built earlier rather than later, such as Divine Ruin (for anti-heal purposes also) and Spear of Desolation (for the wide variety of stats including cooldown reduction).
  
  - Items with a main focus on % penetration (such as Charon's Coin or Obsidian Shard) should typically be built a bit later, when enemy protections are higher and the % pen will be more effective...with that said, Charon's is often built a bit earlier as it requires some stacking, while Ob Shard is usually built 2nd to last or last. Other items with % pen have other purposes besides the pen, so are built anytime, such as Rod of Tahuti, Staff of Myrddin, etc.
  
  
• Which Relics?: For full damage gods that are squishy (like Kukulkan or most damage mages), you almost always will default to 2 relics: Purification Beads first to help you escape hard CC that can lock you down and get you killed, and Aegis Amulet next to help you avoid high incoming damage later in the game. Depending on god and role, other relics are commonly used, but in your situation it sounds like you're just looking at mages right now so I would default to those.
  
  
• Gods Similar to Kukulkan: I honestly would just suggest branching out and trying all of the mages just to see what you might like. But if I'm understanding the situation, mostly the things about Kukulkan that you appreciate right now are the simplicity of his kit. He's got a main AOE damage item that's easy to use on the minion wave. He's got a straightforward line attack in his 1 and ult. He's got something that can help him maneuver/escape.
  
  In keeping with a generally simple kit, the next god I would probably suggest would be Ra. His 1 is a simple line shot that is used for wave clear and is super easy to hit the wave, though is trickier against enemy gods. The other portions of his kit are still simple to understand. Poseidon is another one that you could try.
  
  After that, gods start getting just a bit trickier, whether having to play more positionally sound with good awareness, have certain combos they need to hit with their abilities, or other things. Other gods to consider might be Yu Huang, Raijin, and Discordia perhaps.

But yeah, just keep playing, get more familiar with the game, and start branching out. You want to learn how to play the other gods anyway. Not only will it open up your options, but learning what each god does also helps you understand how to play against them, which is invaluable.

Hope this info helps. If you have more questions on something specific, let us know and we should be able to help more.
