If you know the map like the back of your hand, you can dig up the Tear even with just one obelisk. If someone was willing, I would bet that I could dig it up in 10-15 minutes without any obelisks.

I set myself the task of leveling up Godric into a super-killer. So, I carefully visited all the obelisks. However, in version 3.0, after clearing the entire map, I only managed to level him up to level 23. The cowardly enemies kept running away from the battlefield. It got annoying. So, I finished the mission with an under-leveled Godric.

My daughter has even worse luck with leveling up Godric on her warrior. She cleared the entire territory and defeated several heroes. In 3.0, only the enemies on the hero level know how to run away from the battlefield. However, she only managed to level up Godric to level 22. Now she runs around the entire map, both above and below ground, chasing enemies. They are afraid of her like the devil is of incense - she has 200+ Isabel knights. If Godric is near their castle, they don't even poke their noses out.
