I always found for garen that armor penetration and health runes work the best, but the mastries are good.

As for the items, even for a new player i think it could be balanced better. Everything seemed good until the last whisper came in. I think that maybe instead of the last whisper you could get an infinity edge so she could actually do some damage to enemies. Maybe even a blood thirstier after that but if he is still having health issues it would be okay to put warmog's armor.

The point is that i think that she needs a bit of damage so she can play an offensive role (even if small).

Hello, this is actually a guide for a friend (a female one) so is a non-skilled build with a non-skilled runes, we are talking about easy mode garen, but ty for the ideas, will change some things later.

Since I can't understand this, let me do this in english then, ok?

1) I would prefer a flash over ghost but your choise.

2) Runes. WTF CDR glyphs? No, solotop should never have anything CDR from runes, you just can't go with MR per lvl, huh? :P

3) Items. Please. Rushing sunfire is really weak, this item falls lategame. Instead you just can rush warmog -> atmas. And I don't really prefer last whisper so early on, when they have armor, take it. And maybe replace sunfire with GA / Randuins, more viable imo tho.

Hopefully this will help :3
