Managed to find ALL TEs in my run tonight. Each of them is held off by Avatar Idols (Not Icons), and gives the respective TEs. Enjoy.
Oh, and information on whats guarding what:
Bottom-most 10 minute is guarded by 2 yags around it, and another yag or two on bridge. The other 2 10 minutes are guarded by a simple Ninja, and are easy to clear. The West-most 15 minute is guarded by 4 yags, with 1 roaming bridge guard and 1 at mouth of bridge, I recommend clearing the 2 on bridge then sac the Idol onto the bridge then assume ganking positions.
The northmost Idol is at the bottom of house of the hero, guarded by 2 Summoners. Tricky one to get, probably another sac-gank, only fought it twice so no real strat for it. What we ended up doing was sleeping the avatars, killing the oracles since there is only 2, then going for the stat.
