1. Increasing the Servant's Attack stat - Attack is extremely limited, tied to the Servant's normal caps from leveling, +1000 normal Four bonus, and whatever the equipped CE can provide.

2. Increasing the Servant's Card Type Up bonus - You can get a +50% bonus to one card type before you start a battle by using one of the blue (Arts), green (Quick), or red (Buster) beans. Otherwise, this is a pretty hard stat to raise, as very few Servants have a skill to buff it, let alone apply it to someone else. Merlin is the defacto Buster buffer, likewise for Tamamo and Arts. Quick doesn't have a nice buffer, but Atalante could work I guess.

3. Increasing the Servant's Attack Up bonus - This is the most common buff/debuff type in the game. Things like Charisma and Liz's Torture Techniques (applies Defense Down to a target) cause a positive increase in this modifier.

4. Increasing the Servant's Power Up bonus - Most of your improved damage this event is going to come from this modifier. This is obtained from Golden Sumo (equipped Servant only), Lunar Hot Springs (party-wide), raid-related Servant bonus (refer to the tab above that goes over that), and the raid wave's special bonus (+25%/+50%/+100%/+150%/+200% for increasing difficulty). Also, things that provide NP Power Up and Crit Damage Up will add into this modifier, but, since you'll have a fairly large value from the previously mentioned Power Up sources, these increases will be fairly trivial.

Once you have all that in mind, you basically wait until you have a Brave chain ready on your main damage dealer, activate every buff you can, and burn the raid boss down.
