Hello Ironboy32, I'm Crs Dekar, a Diamond Riven main. Let me be the first to comment on your guide.

Here's some things you may want to consider including:
- Are there times where LS or Doran's blade are good starting items? If so, when?
- Is Titanic a good option to rush? I feel like black cleaver or hydra would give much better stats for you early game, especially with Hydra being able to be activated during q
- For your Titanic path, I would get a spectral's cowl to sit there after dead man's plat. My reasoning for this is that it gives some of the best stats vs ap casters in the game.
- I think Hexdrinker/Maw are very viable on Darius. Hexdrinker can be built early and then upgraded as 4th-6th item
- As for your situational items, I would enjoy it if you put QSS as the item and then mentioned upgrading it later.
- I don't think that Bloodthirster really has a place even if you're fed, I would just take Hydra with Black cleaver and Sterak's gage. This provides you with extreme health values on top of base resistances. You would still get insane damage with this, but you would be nearly impossible to kill, and have the option of switching to titanic at any point you want.
- I don't think Banner has any place. I apologize for being so brief but if you want aegis item, locket is your go to. I think Zz'rot may have a place, if you're wanting to push, this is much better than Banner Imo
- Try to be slightly less casual and more specific with your matchups section. I think saying something like "Soooo easy after level 4" doesn't really explain much about it. Also, your Riven section isn't very detailed, if the lane is hard, focus on ways to win it.
- Look to Jhoijhoi's guide for coding Here
- You can change the sizes of texts with the A button nxt to the normal (B I and U) icons.
- You can also change the color of your text with the palette there, however, I like using This site and popping the code it gives you into the standard color code Instead of using "00ff00" you would use whatever code for color you want that you get with the site.
- Please do break up some of your large sections of text, it can be gruelling to read.
