Source Of Denial is one of the new Runescape achievements which is actually really easy to achieve and can be done in 1 minute. Basically you need to pick fruit from a Sq’irk tree in the Sorceress’s Garden without stopping and it awards 10 runescore points. One has to start right beyond the entrance gate and pick a fruit from the tree without stopping. Running is imperative, and it is done most easily in the winter garden.
Go winter and look for this position:
When you see the spirit click on the sq’irk tree and let your pixels do the running – as you near the tree click on it again so it picks it straight up.
