The most recommended paladin sub-class in Baldur's Gate 3 is the warlock, because this class can be used to kill enemies at close range, slay magic at a distance, and explode with magic. It is a very good choice for use on the battlefield.
Paladin sub-class recommendation: Warlock
The main purpose is to be able to hit more Holy Slash at the spell position, which can be used to close the Holy Slash and far away and can cause magic explosion.
At the same time, on this basis, it can also give teammates a permanent aura, which is a very good choice in this version.
When using this profession, you must pay attention to guarding your bottom line and not make casual attacks.
Mainly increase strength (mainly increase if you play with power weapons), physical fitness, mainly increase charm (mainly increase if you play with agility weapons)
half elf
The sub-class I recommend is Oath of the Ancient Sages . The additional action of this class is that it can provide a group recovery effect for two rounds.
It can also be recovered in the action position, so it is a very good choice to bring on the battlefield.
