This can work but the builds that really shine are the ones that buff at least one key skill from that second class. Sometimes your second class is just there for support. IвЂ™ve theorycrafted more than one build where I put together a bunch of legendaries that buff and convert the damage of a skill I want to use, and then go build it in grimtools only to realize that none of those items give any useful +skills to my chosen secondary class. These are harder to judge class comboвЂ™s on and most often really comes down to the various +skills on the items you need to use. Some skills donвЂ™t have sets dedicated to them, like AAR for example which has a chaos set but otherwise builds are just using various specific items to buff its damage and convert it to fire or lightning or cold. Maybe thatвЂ™s OK if theres a specific reason to play that class but usually its a good sign that it isnвЂ™t optimal. Nightblade is primarily Dual Wield melee character. And for acid- Oathkeeper and then Occultist but itвЂ™s tougher. For cold you want either Inquisitor or Shaman as support class. You can play Trozans TSS with a mage hunter for example, but most of your items wonвЂ™t have any inquisitor +skills on them and there wonвЂ™t be any special bonuses for inquisitor skills either (like adds X damage, modifies the skill). For damage type you have the options: Cold, Pierce and Acid. The same goes for major legendaries like weapons or amulets that modify a skill in a big way, you can usually look at what secondary skills they modify and if there are +skills for other class skills on it.ДЇor example, if you want to focus on TSS, you can look at Trozans set and see that it supports shaman and occultist skills in addition to TSS. This gives you a good idea of which comboвЂ™s will be best.

Generally if a skill you want to use has a set focusing on it, there will be a couple of secondary abilities from two other classes that are supported by that set as well. FOr the arcanist thatвЂ™s especially important as you donвЂ™t have RR of your own which means you usually only pair well with classes that have elemental/aether and RR.ДЄside from that, I find the best way to figure out what builds work is to look at the sets. The most obvious issue when choosing a class is damage types and RR needs.
