The cross skills of Monk are Feint, Foresight, Skull Sunder, Keen Flurry, Fracture, Impulse Drive, Bloodbath, Invigorate, Mercy Stroke and Blood for Blood.

Feint is used to slow enemies and reduce damage. If you don’t have a DRG or LNC, you can take it.

Foresight is used to increase defense. If you have problem about surviving physical damage, you can take it.

Skull Sunder is for attack which generates enmity.

Fracture will give you a decent amount of DoT.

Keen Flurry is to increase parry rate. If you need to survive physical damage, you can take one.

Impulse Drive is to attack. The damage will be stronger if dealt at the back of the target.

Bloodbath is to convert damage dealt to HP. It has a pretty good self-healing mechanism.

Invigorate is used for instantly restoring 300 TP. If you want cheap FFXIV Gil, ssegood is a good choice.

Mercy Stroke is to attack which can only applied while enemy is below 20% HP.  It has 90 seconds CD and can only be used when has less than 20% HP. Turn 8 mercy stroke is amazing. It can be used on every dread and the avatar at the end. it’s also the strongest move we get other than our dots and off the GCD. You can buy FFXIV Gil to get best armor. I’ll use it the moment I can, and I won’t even worry about the healing effect. Also turn 8 and turn 9 made me completely drop fracture. DPS gain is so minor compared to the TP cost (T8 issue) and keen flurry was actually useful to survive the double meteor stream dive (T9). The way I see it invigorate, blood for blood, bloodbath, mercy stroke, then the last one is personal preference.

Blood for Blood is to do damage dealt over 20% and damage taken over 25%.
 
Monks can, but the Gladiator/Pugilist note in the summary is still not correct and could confuse people.

Monk can use these skills from Pugilist. As for defensive, you can choose Foresight and Bloodbath. The most offensive are Blood for Blood and Invigorate.

Also invigorate isn’t really offensive, it’s more of an “oh crap” reactive type button if you get low on TP, from that I can tell. Sure, if you have no TP you aren’t doing any damage, but it’s not directly influencing your DPS like Blood for Blood is going to.

As for Impulse Drive, I have noticed that it is pretty effective when stuck in low level dungeons, primarily for trash, due to a lack of skills available at the time. At that juncture and purpose I found it to be just as good to get the Twin Snakes damage buff and stand behind things spamming Impulse Drive, then it was to bother with the usual rotation. Things died just as quick. But yeah, generally, I wouldn’t bring it to higher level parties.
