Editing Warhammer 40,000/9th Edition Tactics/Apocalypse (section)

===Modifiers===
8th edition used to be the era of the modifier, with everything from elder minus 4 to hit cheese to necron Tesla guns activating on a 4+ to hit rather than just a 6 (because who doesn’t want to multiply their initial shots by 7/6).

9th has made everything a whole lot simpler (and less cheesy) by limiting modifiers to just plus or minus 1 once they are all added together. This means that you can still give a unit plus 2 to hit, all that means is that you’ll ignore a minus 1 to hit penalty and still get plus 1 to hit.

There are a few other important changes around modifiers:
*Effects which trigger on a 1 now only trigger on a natural 1, so weapons like plasma are a lot safer to use.
*Strength modifiers are now done after any effects created by a weapon, a S4 marine with a thunder hammer now hits at S9 instead of S10.
*A roll will always succeed on a 6, and always fail on a 1. The exception to this are armour saves, which are always failed on a 1 but can fail if the dice roll required would be higher than 6 (eg. 7+).
