You don’t need a squire in party (I will take in party if I see them, but what I want are their buffs), but their damage buff is better than Blessing/Sacrament combo, which means more damage if you are leveling, the over durability is also nice to have for long dungeons and grind. Now, I don’t think about sell potions, It is a nice extra if you overproducted, but the difference in cost between make your own potions and buy them is huge, around 10times per potion. Now Gem Roost and awakening are way better to make money but you need to build a name to sell awakening. Some people says that Magnus Opus help to make money too, I don’t see how but as I said I haven’t use this skill enough to know how.
Let’s remmember that you are not taking offensive clerics to heal ET, they are dps and they can assist with heal if needed but that is not their job. Now, most of Clerics trying to do ET are builded with cleric>priest3>*>plague doctor or cleric2>>plague doctor so let’s say that you will need to buy Daino scrolls, don’t see why with the current buff expansion, and Barrier. Now let’s see the skills that works with Simoney
Current available skills: Cure, Deprotected Zone, Aukuras, Zalciai, Daino, Monstrance, Restoration, Turn Undead, Barrier, Arcane Energy, Clairvoyance, Forecast
Which other would you buy? Also to make most of those scrolls mean you are not able to do take priest 3, which means your sacrament/blessing is not too strong, another reason to avoid buy buffs. Sorry, but pardoner doesn’t look like a good money maker so far.
