1st - Cultivate -
Plants that you tend to seem to flourish; any plants within half a mile produce twice as much as they normally would. You can speak with animals, plants, and rocks once per day.
4th - For each planar language you speak, you are considered to have Planar Adaptation for that plane.
7th - Pure Focus -
as a free action you enter a Focused state, which lasts for up to 6 + Tier rounds per day, but must persist for at least 1 round. While in this state you have True Seeing constantly, you can Teleport double your speed as a move action, and cannot be flanked or caught flat footed. You can exit this state as a free action, but cannot re-enter the state for at least 1 full round.
10th - You can recover corruption and taint in the same way you restore ability damage. As a full-round action you can touch a creature and accept their corruption/taint into yourself; if the creature is unwilling, you must succeed a touch attack as part of the full-round action. You must take the full amount at one time, and if this would kill you, as you would die you can Consecrate the area within a half mile of where you perished. This area is considered Cultivated (the area produces twice as much as it would). The consecration is permanent unless an equally corrupt creature desecrates the area.
