The shamrock has been released to the top 3 of the St. Patrick's Day contest. They provide "luck" for a short time. They can be used once per day, and their effects can stack with other bonuses. In testing, on their own they were very powerful. When stacked with career and gang bonuses, they were pretty crazy. My suggestion is to use the shamrock AFTER the other temp bonuses are used.

For example, in 100 attacks using a Shogunate against a combat dummy (an opponent that just absorbs damage), my personal results were as follows...

Average damage per hit of 248.3 with new item bonuses on first attack.
Average damage per hit of 204.1 with new item bonuses on second attack.
Average damage per hit of 143.8 with no new item bonuses.

Your mileage will vary. For those who do use them, please let us know what effects you get and how your next attack is (if you got any combat bonuses that is). I'm curious as to how these will alter combat results.
