Just a small guide on the official Bowling Bash implemented on rAthena as of late.
Level - Damage per hit - Max Chain - Gutter Line Size
1 - 140% - 2 - 1
2 - 180% - 3 - 1
3 - 220% - 4 - 2
4 - 260% - 5 - 2
5 - 300% - 6 - 3
6 - 340% - 7 - 3
7 - 380% - 8 - 4
8 - 420% - 9 - 4
9 - 460% - 10 - 5
10 - 500% - 11 - 5
- Bowling Bash knocks the target monster into the direction you last walked into, after the knockback, there will be a 3x3 splash damage around the target cell of the knockback
- Every monsters hit by the splash damage will itself be knocked back one cell into a random direction and causes its own 3x3 splash damage
- Every monster can be hit up to 2 times per bowling bash, after that it will be immune; only on the first hit, it will cause a 3x3 splash itself
- The chain reaction will continue until no new monsters are hit anymore, until the monster is knocked into a wall or until the max number of chains has been reached
- There is a gutter line from coordinates dividable by 40 with a certain size (see table above), at max level that would be 40-44, 80-84, etc.
- On the gutter line monsters are immune to the chain reaction from bowling bash, even if they haven't been hit 2 times yet, instead they will be knocked back by x tiles whereas x is equal to the gutter line size; the initially targetted monsters will always take 1 hit even if on the gutter line
- When there is knockback immunity, targets won't be knocked back by bowling bash, however, the splash will still be around the cell where the target would have ended up if knockback was possible
- Consequently, hitting a target into a wall will cause the chain reaction to stop, even if no knockback is actually possible
Hints:
- Bowling Bash is particularly effective if you have big mobs and also deals nice single target damage (2x500% outside gutter line)
- For smaller mobs it's effective if you can two-hit kill them with BB; otherwise you should run a few cell back after every hit to reunite them
- There are tools that show you the gutter line as well as guides that display the most optimal positions to use Bowling Bash on certain maps
- rAthena offers a configuration "bowling_bash_area" that allows to replace the gutter lines with an area around the caster to make Bowling Bash always chain until the max chain is reached or the target is knocked into a wall or outside that area
