Through different stages in about the first half of the game, you will find several pouches of seeds. The problem lies in where to plant them. Watch the item description and look for any hints such as "grows in shallow salt water" or "clings to rock and thrives near recently excavated stone". All of the places to plant the seeds are going to be in the first world map (i.e. prior to entering the Tree of Eleh map, which shoots you into a different reality and world map). The following are some places where various seeds can be planted. These plants are all used in making different elixirs once you get further into the ruins themselves. Sangaril can make them in the area where you got most of the seeds. Note: You will need to plant the seeds, then leave and complete an adventure before you can gather them up. Note You cannot plant seeds after entering Eleh.

Gramarye: Near wrecked ship at Eleh Caverns. Add Ahurr's Blue Dust.

Rathmoss: At Indubal Prison, go into the lower level and drop into an alcove in the left side of the wall (an unfinished prison cell). You will know that it is the correct one when a box appears and tells you that the earth here is cool and damp. Add Wardstone.

Scarabee: At Hopiris Ruins, before you get onto the boat that takes you into the ruins, go immediately to your right. When you hit an area that tells you there is a lot of sandstone and thick vines, you have your spot. Add Dung Beetle.

Sinew Grass: At Miridan's Pass, plant the seeds in the garden where the creature is located, next to the pond in the spot that shows up as a "cool shady place". Add Heart of Arxes.

Ubbena's Bolt: In shallow waters of Teomura near wrecked ship. Add Nuntara's Spear.

Whenever in solo mode with Sangaril, her backstab skill will usually kill enemies in one hit.

It is better to gather souls with Morbazon before entering Eleh caverns so you can make better gems early on.

Sea Wasp and Lamia Coral which you find in the Hopari Lab.
Aphasian Ray and Water from Unnamed God. The god's name is Ramuli God Of Silence, which is by the laboratory in the arena district.

After you beat the Sepulchre, you can enter a place called Miridian's Pass. Once inside the area, follow the right wall. You will find a trail that leads up into the mountains to a statue called "The White Lady". Equip Sangaril with a crossbow and enter first person view. Aim at the colored gongs in a specific order to raise the bridge up to the statue. Once you get there, you will get 15000 experience points. Shoot the gongs in the following order.

First bridge: Red, Yellow, Blue
Second bridge: Orange, Green, Yellow, Red
Third bridge: Blue, Orange, Red, Yellow, and Green

Once you use a weapon mold, you cannot use it again.
