casual to Intercept
The opportunity that a lightning hit will be intercepted is inversely related to the percentage of lightning rods on the farm that are presently holding a bang ( either pulsing or holding a battery pack ). The claim probability is
chance to intercept = 1 - (number of charged lightning rods / total number of lightning rods)². That is, if none of the lightning rods are presently holding a bang, a lightning hit is 100 % guaranteed to be intercepted. If 50 % of the lightning rods are charged, a lightning hit has a 75 % chance to be intercepted. If 90 % of the lightning rods are charged, a strike has only a 19 % opportunity to be intercepted. At least one lightning rod must be on the farm to have any chance of intercepting a strike. A non-intercepted lightning strike has a base 25 % luck of hitting a feature on the farm, influenced by casual fortune and luck buffs .
- Though it is possible to place lightning rods outside of the farm map, they will never get hit by lightning there, and thus will produce no battery packs.
- Storms (and thus lightning) never occur in Winter. Storms never occur on Ginger Island.
- More lightning will strike the longer the player stays awake, necessitating more lightning rods and giving potential to produce more Battery Packs.
- Placing a lightning rod on a Grass Starter will cause animals to be unable to eat the grass. It can be used as a persistent source of grass expansion.
- 1.4: Lightning Rods are now ready to harvest the day after a storm, instead of 24 hours later. Lightning Rods can now be stacked in a player’s inventory and in chests.
