Total 691% increased damage of the explosion
Say if there is a way to boost the damage of the explosion even more

Few things:

1) No dex from the tree ? You won't be able to take the gems you plan on using and probably most of the gear. If you don't change your tree you will be forced to take gear with +dex rather than some mods giving you dmg or def boosts. With your tree I would suggest getting one jewel conversing either int or str to dex and 1 or 2 +30 dex nodes. Try to get dex to ~ +100.

2) Fireborn gem is wasted with that tree. You use 10 points to get neccessary two jewel slots and other types of dmg... and what you get ? 40 % increase ? One rare jewel with good mods can get you around 30% increase. ONE. To get more jewel slots, with your tree, you need 2-3 points. Wasting 10 points for just that is well...seriously wasting.

Also with your already high increasees from the tree and doryani I don't think getting more makes you much stronger - getting "more" dmg is what you should be aiming, not "more increases" as they are additive and not multiplicative with your dmg. After reaching 100% increase every "10% increase" gives "5% more dmg", after 200% it gives around "3% more" and so on, so on.....

3) Frenzy charges - they give "more" dmg and increase speed. Get "blood rage" spell or think of other way to get them.

4) Your explosions will make more dmg if they will crit. Critical strikes gives "more dmg" so it is something you should be aiming.

Check the wiki:

Damage from burns also are really nice, so try to get more chance for crits and igniting.

5) It doesn't really increase "explosion dmg" (since it is based on monster life) but to your overall dmg it would be good to work on your attack speed and weapon base dmg. I would replease this increae to Aoe range to multistrike, since you would be hitting like 3 times in the time your normally hit once.

If you don't care about this life leech feature of doryani, just get rares with better attack speed and base dmg. Warlord mark gives your life leech anyway.

If you don't care about your defense at all (glass cannon melee - wow), get Oro:

No physical dmg with that one so you would need to replace gem from your main skill setup to more fire-oriented one.

6) Def... seriously. 150% life is minimum for range class, but still it will be kind of weak. But melee need 2-3 times of that. And you have 184% life, don't go for any endurance charges, nor more endurance, nor any armor. You also don't use shield but dual wield doryani. Good that you at least get fortify but even so... your def sux. You need to at least get to mobs before attacking.. so... they will gravely dmg you before you kill first one. If they are ranged even more so. With low density you will manage with just immortal call but deresso arena and maps will be a no no.

You have easy access to both endurance charges (two more from tree, one from currupted belt, maybe one from bandits) and its source (warlord mark) and also to few nice nodes of armour. Since str-based gear will have armour anyway it won't hurt you too much. Go for it.

1) I think dex will be fine with 2 rings that each have 40+ and abyssus also have some dex on it, maybe I have to pick up one dex node

2) I agree now that I look at it again fireborn jewel is wasted and one rare jewel will better

The plan is to scale "Explosion deals base Fire Damage equal to 10% of the corpse's maximum Life" as close to 100% as possible thats why I use many increasees.

3) I will try and see if I can use blood rage for frenzy charges

4) I will not go crit since it is hard to get on this side of the tree, that would be completely different build.

5) I will use multistrike

Oro will be bad for this build because it gives no increased fire damage

6) it is possible to make a build with over 300% life and still have a real build. I will go for a currupted belt but not take any nodes on the tree for endurance charges
