This is much more cost effective than converting far more expensive items later on. At any rate, try to do all your omni-gel conversions before tier 3 items.
With conservative play this supply should last you the rest of the game without any further conversions. This method allows a quick accrual of credits.Īccumulate your omni-gel earlier rather than later-instead of selling your surplus left over from Eden Prime, convert them into omni-gel as these items will only sell for negligible amounts anyway. Whenever you approach the 150 item cap, find a merchant and sell off all the lower tier items, and any items you are not using (as there is no reason to carry around armor / weapons / upgrades you are not using anyway). Repeat this after finishing each of the four missions. Return to the Citadel, and finish all assignments available before progressing in the main storyline. Do the minigame to open each container you find.
Always have someone on your team with Decryption and Electronics. The tier of gear you find is determined by your character's level. The 'tier' of an item determines its price. Getting the Rich Achievement is relatively straightforward.
