My build changed a bit but now i go: start fairy + boots or fairy + wards (wait for 5 gold) rush philo > belt > phage > warmog > trinity / IBG > situational.
If i go IBG phage becomes mallet and depending on how dumb my team mates are i either stay on the dps route PD IE ect. But recently i catch supports going ap and now and now build supportive (or ward at all so i tend to do that as well) in which case i go bulwark / FH. --- It's been so long since I've fought in Midgard.(Freya) [JUS:2492-0202-2363][PokemonD Shadow:4467-7459-9271]
Flask, Pots and Ward - I tend to sell it late game for a situational item. Boots - Upgrade to Mercs/Tabi early on. Avarice - Upgrade it to an Atma's later on. Hydra Warmogs Spirit Visage - I really like this item on GP, I do like to build Runic Bulwark if I can but usually the support and jungler takes care of it.
