@Helilog56 - Porter is not totally wrong in saying, in modern twins you pull collective.
It depends on the situation and type flown.
Done it in the sim quite often - drop the Nr down to 330 (or just the low rpm warning coming on/off/on/off), with the remaining engine in Hi-Mode, later stages low mode)
Sometimes its the only way to get out a situation, if you want to fly and not crash into the trees.
But that is normaly done close to the ground, i.e. fly away after or before decision.
In cruise, depending on the height, you might also consider to gain altitude for the event of the other donk quitting - but you have to be quick to keep Nr then - probably have to flare to keep it while lowering the collective.
