Greetings from the Sands, Evil-Smelling Brother-in-Law of a Camel!

Since my knowedge of the 5th edition is somewhat lacking, I turn to the collective wisdom of the Community.

Is there a 5th edition fire invocation equivalent to the big KABOOM fire spell of the 4th like Destructive Wave and Beam of the Inferno ?

Thanks for your time and answers.

See you in the Sands.

Rise, Flame Rank 4 (pg 204)

"If you succeed, you summon a Manifest Fire Kami (see page 324). It consumes the flammable material, appearing in its position. It obeys you for two rounds, plus additional rounds equal to your bonus successes,"

and it has some mechanics for setting lots of stuff on fire.

or

Fury of Osano-wo Rank 3 (pg 203)

"The target suffers supernatural damage equal to your Fire Ring plus three times your bonus successes. If a target is Incapacitated by this damage, they suffer a critical strike with severity of 8"
and it can scale more

seems like the most Kaboomy i can find in the core book.

When a shugenja performs a fire invocation they can keep three dice with Strife on them to willingly trigger Spiritual Backlash and turn any single-target attack invocation into KABOOM. So Fury of Osano-Wo + Spiritual Backlash = nuclear explosion centered on the shugenja.

... and must be in Fire stance, so Strife also counts as successes, IIRC.
