In Eoanet: /ʙʀ/

Not like it is in any Eoanet word, but it is an allowable cluster, soo...

BRun

/ʙʀun/

'brown'

my conlangs dont have many consonant cllusters lol

The longest one in one of my languages is probably /pkn/

Probably clhv, pronounced [t͡ʃʎv]

It's not in any word however

In Neo-Ruetrique: probably "bqd" /b̪qʰɖ/

I usually avoid consonant clusters in my lang. For example, in suffixes I make consonants appear only when followed by a vowel or certain consonants, ex: y(f)-: yfunkiŝ /ʏ̝f'uŋkɪʃ/, YfReimspron /ʏ̝f’rɛɪ̯m.spron̪/, YBande /ʏ̝'ban̪d̪ə/. I also simplify existing clusters, for example I would modify your cluster in /akse̞ʃke̞d/ or /akse̞ʃkn̩/ (I don't know what is the phonology of your lang excuse me XD). Last but not least, I also separate phonetically the clusters, like /rɛɪ̯m.spron̪/.

My conlang is made of clicks and "clusters" are allowed but they work differently. The most complex is probably ť_pŧ /ǀʘǁ/
