isolation and opportunism for a noob

[deast]

Hello

These are probably things that have already been discussed here but I still have a lot of doubts on these 2 strategies, isolation and opportunism.

I read that are 2 very powerful build but i have some issue to create and to use them.

For opportunism i know that i have to put as many debuffs as possible on as many mobs, to use contagion to spread them when mob killed but i don't understand on which mob to put contagio and which is the best way for a meele hero to put debuff, can someone explain me better?
Is it a good strategies also for other classes and in this case, suggestions?

For isolation, i suppose that it's good to use with wand for mage and hand crossbow for archer but i have doubt on how to isolate the mobs. For ranged i suppose that best way is to use to begin of turn Rain of Arrows of short bow for archer to isolate many mobs and to kill the rest of the mobs with hand crossbow but i not sure.
For mage, i think that with hand i can kill the isolate mob but which spell i have to use to isolate them?

Best Regards

Opprtunism and isolation are indeed very powerful mechanisms. They are global damage, meaning that your total damage will be multiplied by your opportunism/isolation bonus if criterias are met.
Moreover, some weapons have opportunism/isolation bonuses, meaning the bonus gets multiplied even more!
For example: the magic orb has a strong isolation bonus on its first basic attack. It's meant to target only isolated units, otherwise it will do nearly no damage.
Other example: the Sorching wave skill (Power staff) has a strong opportunism bonus. Be sure to apply a debuff before launching it, it will double the damage, at the very minimum!

As a consequence, some weapons are nearly unplayable without theses bonuses. You will need isolation for the orb and dagger (don't play the rifle, trust me). You will need opportunism mostly for the druidic staff also.

However, I would advice you to not rely too much on these mechanisms for basic ennemies. You should be able to kill them with basic attacks, not worrying too much about applying a debuff for example. On the other hand, it's very important, when you fight a boss/elite/tier 6 ennemy etc... to check your opportunism/isolation bonuses and act accordingly. It will increase your damage by a lot!
